According to an influential philosophical view I call “the relational properties view”, “perspectival” properties, such as the elliptical appearance of a tilted coin, are relational properties of external objects. Philosophers have assessed this view on the basis of phenomenological, epistemological or other purely philosophical considerations. My aim in this paper is to examine whether it is possible to evaluate RPV empirically. In the first, negative part of the paper I consider and reject a certain tempting way of doing so. In (...) the second, positive part of the paper I suggest a novel way of evaluating RPV empirically, relying on the influential object files framework. (shrink)

Deep learning may transform health care, but model development has largely been dependent on availability of advanced technical expertise. The aim of this study is to develop a deep learning model to predict the gender from retinal fundus images. The proposed model was based on the Xception pre-trained model. The proposed model was trained on 20,000 retinal fundus images from Kaggle depository. The dataset was preprocessed them split into three datasets (training, validation, Testing). After training and cross-validating the (...) proposed model, it was evaluated using the testing dataset. The result of testing, the area under receiver operating characteristic curve (AUROC) of the model was 0.99, precision, recall, f1-score and accuracy were 99%, precision, recall, f1-score and accuracy were 96.83%, 96.83%, 96.82% and 96.83% respectively.. Clinicians are presently unaware of dissimilar retinal feature variants between females and males, stressing the importance of model explain ability for the prediction of gender from retinal fundus images. The proposed deep learning may enable clinician-driven automated discovery of novel visions and disease biomarkers. (shrink)

Neuroscience hasn’t shown how quite similar sensory circuits encode quite different colors and other qualia, nor how the unified pictorial form of images is encoded, nor how these codes yield conscious images. Neuroscience’s fixation here on cortical codes may be the culprit. Treating conscious images partly as retinal substances may avoid these problems. The evidence for conscious retinal images is that (a) the cortical codes for images are quite problematic, (b) injecting retinas with certain genes turns dichromats into (...) trichromats without cortical help, (c) retinas can discern colors by themselves without cortex, (d) retinal distortions appear in images but cortical distortions don’t, (e) retinal detectors support finely detailed colors, but V4 detectors don’t, due to their big receptive fields, (f) retinal activity has pictorial form, but viable cortical codes for pictorial form don’t exist. So, the colors and unified pictorial form of images arguably arise mainly across arrays of retinal detectors—not from abstract cortical codes. Images may be hidden in retinal activity beyond what EEGs show of it (cf. Strawson’s monism). Also, cortex refines these retinal images but cortical impairment (anesthesia, lesions, etc.) blocks awareness of them, for they’re no longer accessible to the mind’s subject-centered consciousness, resident in cortex. This proposal is largely testable and based in recent evidence. It avoids neuroscience’s elusive, problematic coded images and enigmatic explanations of how they become conscious. (shrink)

This article seeks the origin, in the theories of Ibn al-Haytham (Alhazen), Descartes, and Berkeley, of two-stage theories of spatial perception, which hold that visual perception involves both an immediate representation of the proximal stimulus in a two-dimensional ‘‘sensory core’’ and also a subsequent perception of the three dimensional world. The works of Ibn al-Haytham, Descartes, and Berkeley already frame the major theoretical options that guided visual theory into the twentieth century. The field of visual perception was the first area (...) of what we now call psychology to apply mathematics, through geometrical models as used by Euclid, Ptolemy, Ibn al-Haytham, and Descartes (among others). The article shows that Kepler’s discovery of the retinal image, which revolutionized visual anatomy and entailed fundamental changes in visual physiology, did not alter the basic structure of theories of spatial vision. These changes in visual physiology are advanced especially in Descartes' Dioptrics and his L'Homme. Berkeley develops a radically empirist theory vision, according to which visual perception of depth is learned through associative processes that rely on the sense of touch. But Descartes and Berkeley share the assertion that there is a two-dimensional sensory core that is in principle available to consciousness. They also share the observation that we don't usually perceived this core, but find depth and distance to be phenomenally immediate, a point they struggle to accommodate theoretically. If our interpretation is correct, it was not a change in the theory of the psychology of vision that engendered the idea of a sensory core, but rather the introduction of the theory into a new metaphysical context.

Ein Homunkulus im philosophischen Sprachgebrauch ist eine postulierte menschenähnliche Instanz, die ausdrücklich oder unausdrücklich zur Erklärung der Arbeitsweise des menschlichen Geistes herangezogen wird. Als Homunkulus-Fehlschluß wird die Praxis bezeichnet, Prädikate, die auf kognitive oder perzeptive Leistungen einer ganzen Person zutreffen, auch auf Teile von Personen oder auf subpersonale Vorgänge anzuwenden, was typischerweise zu einem Regreß führt. Der vorliegende Beitrag erörtert den Homunkulus-Fehlschluß zunächst in argumentationstheoretischer Hinsicht und stellt dabei ein Diagnoseschema auf. Dann werden zwei Anwendungsfelder erörtert: Instanzenmodelle der Psyche (Platon, (...) Freud) sind ihrer Natur nach homunkulusgefährdet, denn es ist aufgrund der holistischen Zuschreibungsbedingungen mentaler Fähigkeiten schwer plausibel zu machen, wie eine innerpsychische Instanz den ihr zugedachten Beitrag leisten soll, ohne über eine eigene Psyche zu verfügen. Der zweite Anwendungsfall ist das Problem des invertierten Netzhautbildes in der Philosophie der Wahrnehmung, das wissenschafts- und philosophiegeschichtlich eingebettet und unter besonderer Berücksichtigung von Descartes diskutiert wird. Schließlich werden offensive Rechtfertigungen homunkularer Redeweisen erörtert und größtenteils zurückgewiesen. -- The homunculus fallacy is committed when someone tries to explain how the human mind works by postulating a little man within the mind or the brain. Homunculi are rarely posited with one’s eyes open. Rather, the fallacy occurs when predicates that properly apply to cognitive or perceptual achievements of persons get applied to subpersonal processes or to parts of persons (e.g., brains). The paper suggests a pattern for diagnosing homunculus fallacies. After taking a look at Freud’s and Platon’s homuncular metapsychologies, a case study is discussed in detail: the problem of the inverted retinal image which plagued the philosophy of perception since Kepler formulated it in 1604. It is argued that the irradiation patterns on the retina are not images, on pain of committing the homunculus fallacy. The paper closes with the repudiation of some frank apologies of homuncular explanations. (shrink)

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted (...) coin retain an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Ecological Psychology and Enactivism both challenge representationist cognitive science, but the two approaches have only begun to engage in dialogue. Further conceptual clarification is required in which differences are as important as common ground. This paper enters the dialogue by focusing on important differences. After a brief account of the parallel histories of Ecological Psychology and Enactivism, we cover incompatibility between them regarding their theories of sensation and perception. First, we show how and why in ecological theory perception is, crucially, (...) not based on sensation. We elucidate this idea by examining the biological roots of work in the two fields, concentrating on Gibson and Varela and Maturana. We expound an ecological critique of any sensation-based approach to perception by detailing two topics: classic retinal image theories and perception in single-celled organisms. The second main point emphasizes the importance of the idea of organism-environment mutuality and its difference from structural coupling of sensations and motor behavior. We point out how ecological - phenomenological methods of inquiry grow out of mutualism and compare Gibson’s idea of visual kinesthesis to Merleau-Ponty’s idea of the lived body. Third, we conclude that Ecological Psychology and varieties of Enactivism are laying down different paths to pursue related goals. Thus, convergence of Ecological Psychology and Enactivism is not possible given their conflicting assumptions, but cross-fertilization is possible and desirable. (shrink)

Aristotle held that perception consists in the reception of external sensory qualities (or sensible forms) in the sensorium. This idea is repeated in many forms in contemporary philosophy, including, with regard to vision, in the idea (still not firmly rejected) that the retinal image consists of points of colour. In fact, this is false. Colour is a quality that is constructed by the visual system, and though it is possible to be a realist about colour, it is completely (...) misleading to think of it as received by the retina. Moreover, such supposedly “charitable” interpretations of Aristotle’s doctrines, based on miscon- ceptions of perception-science, distort our understanding of his historical context. (shrink)

The quantization error in a fixed-size Self-Organizing Map (SOM) with unsupervised winner-take-all learning has previously been used successfully to detect, in minimal computation time, highly meaningful changes across images in medical time series and in time series of satellite images. Here, the functional properties of the quantization error in SOM are explored further to show that the metric is capable of reliably discriminating between the finest differences in local contrast intensities and contrast signs. While this capability of the QE is (...) akin to functional characteristics of a specific class of retinal ganglion cells (the so-called Y-cells) in the visual systems of the primate and the cat, the sensitivity of the QE surpasses the capacity limits of human visual detection. Here, the quantization error in the SOM is found to reliably signal changes in contrast or colour when contrast information is removed from or added to the image, but not when the amount and relative weight of contrast information is constant and only the local spatial position of contrast elements in the pattern changes. While the RGB Mean reflects coarser changes in colour or contrast well enough, the SOM-QE is shown to outperform the RGB Mean in the detection of single-pixel changes in images with up to five million pixels. This could have important implications in the context of unsupervised image learning and computational building block approaches to large sets of image data (big data). (shrink)

The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role of the discs in rods and cones, 3) how inverted images on the retina are converted to erect images for visual perception, 4) what portion of the image formed on the retina is actually processed in the brain, 5) the reason we have an after- (...) class='Hi'>image with antagonistic colors, and 6) how we remember space. This theoretical article attempts to clarify some of the physiological processes involved with human vision. The global integration of visual information is conceptual; therefore, we include illustrations to present our theory. Universally, the eyeball is 2.4 cm and works together with membrane potential, correspondingly representing the retinal layers,photoreceptors, and cortex. Images formed within the photoreceptors must first be converted into chemical signals on the photoreceptors’ individual discs and the signals at each disc are transduced from light photons into electrical signals. We contend that the discs code the electrical signals into accurate distances and are shown in our figures. The pre-existing oscillations among the various cortices including the striate and parietal cortex,and the retina work in unison to create an infrastructure of visual space that functionally ‘‘places” the objects within this ‘‘neural” space. The horizontal layers integrate all discs accurately to create a retina that is pre-coded for distance. Our theory suggests image inversion never takes place on the retina,but rather images fall onto the retina as compressed and coiled, then amplified through lateral inhibition through intensification and amplification on the OFF-center cones. The intensified and amplified images are decompressed and expanded in the brain, which become the images we perceive as external vision. (shrink)

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain (...) activity with relatively high integrated information (Phi) compared to veridical visual perceptions. We then present filled/non-filled pairs as an empirical challenge to the integrated information theory of consciousness, which predicts that phenomenologically identical experiences depend on brain processes with identical Phi.

There are many eye diseases but the most two common retinal diseases are Age-Related Macular Degeneration (AMD), which the sharp, central vision and a leading cause of vision loss among people age 50 and older, there are two types of AMD are wet AMD and DRUSEN. Diabetic Macular Edema (DME), which is a complication of diabetes caused by fluid accumulation in the macula that can affect the fovea. If it is left untreated it may cause vision loss. Therefore, early (...) detection of diseases is a critical importance. Our main goal is to help doctors detect these diseases quickly before reaching a late stage of the disease. In ophthalmology, optical coherence tomography (OCT) is critical for evaluating retinal conditions. OCT is an imaging technique used to capture high-resolution cross-sections of the retinas of patient. In this thesis, we review ways and techniques to use deep learning classification of the optical coherence tomography images of diseases from which a Retinal is suffering. The models used to improve patient care are (VGG-16, MobileNet, ResNet-50, Inception V3, and Xception) to reduce costs and allow fast and reliable analysis in large studies. The obtained results are encouraging, since the best model ResNet-50 reaching 96.21% of testing accuracy, which is very useful for doctors, to diagnose retinal diseases. (shrink)

Current research on the various forms of autoscopic phenomena addresses the clinical and neurological correlates of out-of-body experiences, autoscopic hallucinations,and heautoscopy. Yet most of this research is based on functional magnetic resonance imaging results and focuses predominantly on abnormal cortical activity. Previously we proposed that visual consciousness resulted from the dynamic retinogeniculo-cortical oscillations, such that the photoreceptors dynamically integrated with visual and other vision-associated cortices, and was theorized to be mapped out by photoreceptor discs and rich retinal networks which (...) synchronized with the retinotopic mapping and the associated cortex. The feedback from neural input that is received from the thalamus and cortex via retinogeniculo-cortical oscillations and sent to the retina is multifold higher than feed-forward input to the cortex. This can effectively translate into out-of-body experiences projected onto the screen formed by the retina as it is perceived via feedback and feed-forward oscillations from the reticular thalamic nucleus, or “internal searchlight”. This article explores the role of the reticular thalamic nucleus and the retinogeniculo-cortical oscillations as pivotal internal components in vision and various autoscopic phenomena. (shrink)

The concept of ‘the image’ can be given historical, conceptual, aesthetic and moral specifications. This essay sets out some of the scholarly issues in the dense semantic field of ‘the image’. In particular, the essay considers how the meaning of the image is often determined in relation to the opposition between sensible form and intelligible idea. Specific attention is given to Kantian aesthetics, which inaugurates a specific way of understanding the sensible form as a mode of processing (...) moral ideas. (shrink)

The senses present their content in the form of images, three-dimensional arrays of located sense features. Peacocke’s “scenario content” is one attempt to capture image content; here, a richer notion is presented, sensory images include located objects and features predicated of them. It is argued that our grasp of the meaning of these images implies that they have propositional content. Two problems concerning image content are explored. The first is that even on an enriched conception, image content (...) has certain expressive limitations. In particular, it cannot express absolute location and time (as opposed to spatiotemporal relations) or logical complexity. Yet, perceptual experience does seem to express certain absolute locations—namely, here and now. How can it do so? Secondly, image content cannot exhaust the significance of perceptual states. This is proved by noting that perception, memory, and anticipation can have the same image content. Yet they have different significance. These problems show that some of the significance of sensory states comes from outside the image. (shrink)

Some have suggested that images can be arguments. Images can certainly bolster the acceptability of individual premises. We worry, though, that the static nature of images prevents them from ever playing a genuinely argumentative role. To show this, we call attention to a dilemma. The conclusion of a visual argument will either be explicit or implicit. If a visual argument includes its conclusion, then that conclusion must be demarcated from the premise or otherwise the argument will beg the question. If (...) a visual argument does not include its conclusion, then the premises on display must license that specific conclusion and not its opposite, in accordance with some demonstrable rationale. We show how major examples from the literature fail to escape this dilemma. Drawing inspiration from the graphical logic of C. S. Peirce, we suggest instead that images can be manipulated in a way that overcomes the dilemma. Diagrammatic reasoning can take one stepwise from an initial visual layout to a conclusion—thereby providing a principled rationale that bars opposite conclusions—and the visual inscription of this correct conclusion can come afterward in time—thereby distinguishing the conclusion from the premises. Even though this practical application of Peirce’s logical ideas to informal contexts requires that one make adjustments, we believe it points to a dynamic conception of visual argumentation that will prove more fertile in the long run.

Most research on image schema examined the meaning configuration of words connotation. However, previous studies of adjectives are meaningful in cognitive linguistics because they provide insight into how those adjectives are involved with psychological movement. In this sense, from the perspective of cognitive linguistics, one’s conceptualization and cognition are closely associated with their bodily experience and surroundings; adjectives are no exception. The varieties of transformations of image schemas lay the foundation for the conception and perception. Accordingly, this study (...) is an investigation into the perception of adjectives and psychological activities associated with image schema. Data in this study come from adjectives in the novel The Great Gatsby, which were tagged and calculated with the help of software Python and the NLTK package. The results demonstrate that a significant amount of adjectives were used in the novel. Moreover, Nick’s psychological activities changed significantly from the SOURCE to the DESTINATION schematic stage, which is uncovered by his expression of adjectives. Finally, the results further suggest that transformations of image schema as BALANCE, CONTAINER, and PATH work together to motivate one’s linguistic expression of adjectives. The present findings have several implications for research on lexicons and literacy interpretation from cognitive linguistics. (shrink)

Advanced medical imaging, such as CT, fMRI and PET, has undergone enormous progress in recent years, both in accuracy and utilization. Such techniques often bring with them an illusion of immediacy, the idea that the body and its diseases can be directly inspected. In this paper we target this illusion and address the issue of the reliability of advanced imaging tests as knowledge procedures, taking positron emission tomography in oncology as paradigmatic case study. After individuating a suitable notion of reliability, (...) we argue that PET is a highly theory-laden and non-immediate knowledge procedure, in spite of the photographic-like quality of the images it delivers; the diagnostic conclusions based on the interpretation of PET images are population-dependent; PET images require interpretation, which is inherently observer-dependent and therefore variable. We conclude with a three-step methodological proposal for enhancing the reliability of advanced medical imaging. (shrink)

This essay explores Jonas’s multifaceted and rich enquiries into the notion of image. In particular, it argues that reflecting on the “image” helps Jonas clarify the unique condition of human existence, where the twine of thought and being reveals a paradoxical (and yet crucial) relationship between time and eternity, change and permanence, immanence and transcendence. The employ of the interpretative device provided by the image enables a nuanced understanding of the human complexity which goes beyond the partial (...) and reductive descriptions of relativistic immanentism, on the one hand, and immutable transcendence, on the other. By commenting upon its anthropological, aesthetic, and ethical significance, we propose that the study of Jonas’s thoughts on the image not only offers valuable insights into the philosophical understanding of such a fascinating object, but also sheds a new and interesting light on the unity of his oeuvre.

Without doubt, there is a great diversity of scientific images both with regard to their appearances and their functions. Diagrams, photographs, drawings, etc. serve as evidence in publications, as eye-catchers in presentations, as surrogates for the research object in scientific reasoning.

Downes who takes this diversity as a reason to argue against a unifying representation-based account of how visualisations play their epistemic role in science. In the following paper, I will suggest an (...) alternative explanation of the diversity of scientific images. This account refers to processes which are caused by the social setting of science. What exactly is meant by this, I will spell out with the aid of Ludwik Fleck’s theory of the social mechanisms of scientific communication. (shrink)

Ontology is one strategy for promoting interoperability of heterogeneous data through consistent tagging. An ontology is a controlled structured vocabulary consisting of general terms (such as “cell” or “image” or “tissue” or “microscope”) that form the basis for such tagging. These terms are designed to represent the types of entities in the domain of reality that the ontology has been devised to capture; the terms are provided with logical defi nitions thereby also supporting reasoning over the tagged data. Aim: (...) This paper provides a survey of the biomedical imaging ontologies that have been developed thus far. It outlines the challenges, particularly faced by ontologies in the fields of histopathological imaging and image analysis, and suggests a strategy for addressing these challenges in the example domain of quantitative histopathology imaging. The ultimate goal is to support the multiscale understanding of disease that comes from using interoperable ontologies to integrate imaging data with clinical and genomics data. (shrink)

This qualitative case study investigates the environmental implications of tourist arrivals in Matabungkay Beach, Lian, and their impact on the destination image. Through in-depth interviews with seven key stakeholders, including local residents, business owners, and environmental activists, the study explores perceptions, concerns, and potential solutions regarding the intersection of tourism and environmental sustainability. Findings reveal a complex relationship between tourism and environmental degradation, with participants expressing concerns about poor waste management, impacts on destination image, and health concerns. These (...) challenges not only threaten the natural beauty and biodiversity of the area but also tarnish the destination's image, affecting its appeal to tourists and potential investors. Despite these challenges, participants highlight existing initiatives and potential solutions, including community-based conservation efforts, sustainable tourism practices, and enhanced regulations. Collaboration among stakeholders is emphasized as crucial for achieving a balance between tourism development and environmental preservation. The study underscores the need for comprehensive strategies includes formulated an ordinance for comprehensive waste management and pollution control ordinance to optimize the destination image of Matabungkay Beach while addressing its environmental challenges. By integrating sustainable practices and fostering community engagement, the destination can enhance its appeal while safeguarding its natural resources for future generations. (shrink)

Although better known for his phenomenology of perception and the perceived world, Merleau-Ponty’s writings also contain the outlines of a rich and unique account of the imagination and the imaginary. In this paper, I explicate the phenomenology of the image that Merleau-Ponty develops throughout his work. I show how Merleau-Ponty develops this account of the image in critical response to Sartre and in a way that follows from his own descriptions of what painters do when they paint and (...) of what we experience when we look at their paintings. The investigation of the particular mode of being of images leads to a consideration of the body and Merleau-Ponty’s later ontology. (shrink)

In this paper, I begin with an account of the initial distinction between likenesses and appearances, a distinction which may resemble the difference between sophists and philosophers. That distinction first arises immediately after the puzzling appearance of the noble sophist, who seems to occupy an odd space in between sophist and philosopher. In the second section, I look more closely at the noble sophist, and on what that figure might tell us about images and the use of images. I also (...) attempt to use the insights provided by the noble sophist in an investigation of the kind of images that Plato the author produces. This raises the question of the general notion of image as it appears in the Sophist, and especially of the dual nature of all images, which in turn invites reflection on certain features of the examination of being and non-being late in the dialogue. Finally, I return to the deception inherent in images, and I argue that this dialogue does not present the possibility of completely honest images. Nevertheless, I hope to show that some uses of deceptions and images are better than others. (shrink)

The paper is an introduction to the third issue of the Journal for the Philosophy of Language, Mind and the Arts. The authors give an account of the theories that have most enriched the study of images since the second half of the twentieth century: analytical philosophy and visual culture studies. A distinction is made between the two philosophical traditions. On the one hand, in particular within the context of analytic philosophy, images have been studied as single entities in relationship (...) with both a referent and the perceptual or interpretive abilities of an observer. On the other hand, thanks in particular to the iconographic tradition inaugurated by Aby Warburg, images have been analyzed in their multiplicity, in their mutual relationship, both synchronically and diachronically.

In contemporary healthcare, medical image categorization is essential for illness prediction, diagnosis, and therapy planning. The emergence of digital imaging technology has led to a significant increase in research into the use of machine learning (ML) techniques for the categorization of images in medical data. We provide a thorough summary of recent developments in this area in this review, using knowledge from the most recent research and cutting-edge methods.We begin by discussing the unique challenges and opportunities associated with medical (...) image classification, including the complexity of anatomical structures, variability in imaging modalities, and the need for interpretability and reliability in clinical settings. Subsequently, we survey a wide range of ML algorithms and techniques employed for medical image classification, including traditional methods such as support vector machines and k-nearest neighbors, as well as deep learning approaches like convolutional neural networks (CNNs) and recurrent neural networks (RNNs). Furthermore, we examine key considerations in dataset preparation, feature extraction, and model evaluation specific to medical image classification tasks. We highlight the importance of large, annotated datasets, transfer learning, and data augmentation techniques in enhancing model performance and generalization. (shrink)

There is the tension between, on the one hand, Wittgenstein’s not giving theoretical weight to metaphor, and on the other, his exuberant use of it. On a more fundamental level, there is a straightforward contradiction between Wittgenstein’s claim of the primordial literalness of everyday language, and his stress on the multiplicity and flexibility of language-games. Wittgenstein’s problem was that he did not succeed in making his ideas on metaphor, and indeed his ideas on metaphor and images, converge with the main (...) drift of TS 227 (the so-called ‘Part I’ of the so-called ‘Philosophical Investigations’). It was this divergence, I believe, that prevented him from rounding out his later philosophy. (shrink)

In his 1903 Syllabus, Charles S. Peirce makes a distinction between icons and iconic signs, or hypoicons, and briefly introduces a division of the latter into images, diagrams, and metaphors. Peirce scholars have tried to make better sense of those concepts by understanding iconic signs in the context of the ten classes of signs described in the same Syllabus. We will argue, however, that the three kinds of hypoicons can better be understood in the context of Peirce's sixty-six classes of (...) signs. We analyze examples of hypoicons taken from the field of information design, describing them in the framework of the sixty-six classes, and discuss the consequences of those descriptions to the debate about the order of determination of the 10 trichotomies that form those classes.

When we try to understand what a picture represents, how we experience the picture, I argue, plays a key role in determining the content the picture represents. More specifically, I argue that understanding pictorially represented content requires two tasks—visually grasping the picture’s design (an image) and interpreting what the design represents (what it is an image of). Neither task is done without the other, meaning that the viewer’s success in the former—visually identifying the image—depends on their success (...) in the latter—determining what the image is of. Because of this interdependence, I argue, when the viewer succeeds in understanding the picture, they find their interpretation of the picture perceptually convincing. (shrink)

The possibilities of depicting non-existents, depicting non-particulars and depictive misrepresentation are frequently cited as grounds for denying the platitude that depiction is mediated by resemblance. I first argue that these problems are really a manifestation of the more general problem of intentionality. I then show how there is a plausible solution to the general problem of intentionality which is consonant with the platitude.

The third issue of the Journal for the Philosophy of Language, Mind and the Arts is centered on a series of questions related to the nature of images. What properties characterize them? Do they exist also in our minds? What relationship do they have with phenomena such as perception, memory, language and interpretation? The authors participating in this issue have been asked to answer these and other questions starting from and in dialogue with the two philosophical perspectives that have most (...) enriched the study of our object of research since the second half of the twentieth century: analytical philosophy and visual culture studies. The first four essays address problems related to ontology (Didi-Huberman, Prinz, Bantinaki, Manzotti). In their pages the question will be asked not only about the nature of images but also about what it means for an image to represent an object or an action realistically. The second part contains discussions related to the topics of perception, appreciation and creation of pictures (Ferretti; Gavaler, Goldberg; Pigoni, Coraci, Carlenzi). The third section goes through the problems related to the very concept of representing by images (Biggs; Weichert; Derby). The last section of the issue is devoted to two cases in which images are used not so much and not only to represent something, but also to convey ethical-political values (Fasnacht; Olesiejuk).

I begin by reviewing recent research by Merleau-Ponty scholars opposing aspects of the critique of Merleau-Ponty made by Meltzoff and colleagues based on their studies of neonate imitation. I conclude the need for reopening the case for infant self-other indistinction, starting with a re-examination of Merleau-Ponty’s notion of indistinction in the Sorbonne lectures, and attending especially to the role of affect and to the non-exclusivity of self-other distinction and indistinction. In undertaking that study, I discover the importance of understanding self-other (...) distinction and indistinction in terms of their affective significance. For Merleau-Ponty, self-other indistinction is a virtual or imaginary participation in others’ orientations that he defines as an affective phenomenon. Further, Merleau-Ponty’s account of the advent of the body proper—the aspect of the body image that circumscribes the body as a distinct and private space—theorizes it as an affective innovation. Rather than being a fact of which we at first are ignorant and gradually grow to recognize, distinction from others in the sense that is important to Merleau-Ponty is a situation that must be cultivated and maintained through the negotiation of affective intimacy. Understanding indistinction and distinction in terms of the affective forces that sustain them explains how it is possible for them to coexist. (shrink)

What role do images play in philosophical persuasion? With the advent of bio-art in the 1990s, a new vista opened up for this age-old puzzle: the possibility of creating images through bioengineering of living matter. Here, I test the critical intentions of bio-artists by setting up a comparison between, on the one hand, bio-art, and on the other, bioethics, a philosophical discipline, which developed at around the same time as this new artform. I argue there is an aspect of ethics--'the (...) difficulty of reality' in Cora Diamond's coinage--which analytic bioethics obscures, and which art can help us come to terms with. I develop my argument by comparing the work of artists Eduardo Kac, Stelarc and Maja Smrekar, with utilitarian bioethics by philosophers like Julian Savulescu. Philosophical concepts of the living presence, the viral image and the pensive image are revisited through this inquiry. (shrink)

This chapter explores the role that non-textual narrations of biblical stories can play in Christian life and practice. Our case study is the Shrine of Divine Mercy in Kabuga, Rwanda. The stations at the shrine tell the story of Jesus’s life and passion, incorporating images from the Catholic devotional tradition of Divine Mercy and elements evoking the Rwandan genocide. While many philosophical accounts of narratives presuppose that narratives are textual, material and visual art like the Kabuga shrine can also be (...) narrative, in that, like text, material and visual art can selectively represent multiple events and connections between them. We argue that material-visual narratives like the shrine can be effective in achieving commonly identified functions of narratives, such as focusing attention, immersing in a story, engaging the emotions, and fostering a common perspective on the world. We further argue that material-visual art is well-suited to narrating the Gospel in particular, for it can present the Gospel story alongside other stories (in this case, the story of the Rwandan genocide) and in so doing reframe these other stories in light of the Gospel.

My topic is a certain view about mental images: namely, the ‘Multiple Use Thesis’. On this view, at least some mental image-types, individuated in terms of the sum total of their representational content, are potentially multifunctional: a given mental image-type, individuated as indicated, can serve in a variety of imaginative-event-types. As such, the presence of an image is insufficient to individuate the content of those imagination-events in which it may feature. This picture is argued for, or (more (...) usually) just assumed to be true, by Christopher Peacocke, Michael Martin, Paul Noordhof, Bernard Williams, Alan White, and Tyler Burge. It is also presupposed by more recent authors on imagination such as Amy Kind, Peter Kung and Neil Van Leeuwen. I reject various arguments for the Multiple Use Thesis, and conclude that instead we should endorse SINGLE: a single image-type, individuated in terms of the sum total of its intrinsic representational content, can serve in only one imagination event-type, whose content coincides exactly with its own, and is wholly determined by it. Plausibility aside, the interest of this thesis is also in its iconoclasm, as well as the challenge it poses for the diverse theories that rest on the truth of the Multiple Use Thesis. (shrink)

This article examines Machiavelli’s image of humanity. It argues against the prevailing views that characterize it either as pessimistic or optimistic and defends the thesis that the Florentine has a realist image of humanity. Machiavelli is a psychological egoist who conceives of man as a being whose actions are motivated by his drives, appetites, and passions, which lead him often to immoral behavior. Man’s main drives are “ambition” (ambizione) and “avarice” (avarizia). This article also investigates Machiavelli’s concept of (...) nature and shows that, for him, the constancy of human nature is the central premise that makes the scientific analysis of politics possible. Despite the fact that human drives and capabilities are the same at all times, good laws, military training, and religion allow man to be changed and educated toward “virtue” (virtù). To make such changes in man, however, presupposes a good legal and political order. Machiavelli justifies the state because of its capacity to reshape human nature and to improve man. The state is not only a coercive power but a moral institution. This leads to the conclusion that Machiavelli does not separate politics from morality as most scholars claim. (shrink)

The new edition of the papiri of the second book of 'Peri Phuseos' allows for a detailed reconstruction of the mechanisms of vision. Some of the characteristic features of images according to Epicurus are presented here for the first time. One of the problems is the congruence between the representation and the object from which it originates: i.e. the truth of the image.

Man has built tools to extend his visual experience in order to explore reality beyond his sensory capacity, for example microscopes, telescopes, high shutter speed and infrared cameras. However he has yet to build a tool to fully explore visual realms beyond his ordinary cognitive faculties. With the development of computing, comes the possibility of building a tool to explore the virtual forms/spaces of images that are ordinarily inaccessible to the mind. This article identifies how cognition is ordinarily limited and (...) posits a way of going beyond those limits, by defining a computational model of how those virtual forms/spaces might be created. This definition is based on brief but repeated empirical experiences of ‘higher order’ manifestations. (shrink)

The overarching theme of Locke’s Image of the World, by Michael Jacovides, is that Locke’s belief in the best science of his day shapes his philosophy in important ways. Jacovides contends that “by understanding the scientific background to Locke’s thoughts, we can better understand his work” (1), including both his positions and his arguments for those positions. To a lesser extent, Jacovides’s book also treats Locke as a case study in thinking about how much scientific theory should influence philosophy. (...) While much of the science Locke relies on is incomplete or problematic, and so leads him into errors, Jacovides is sympathetic to Locke’s approach of using the best scientific theories to help develop and justify his philosophical positions. Throughout the book Jacovides shows how science – Locke’s study of medicine, and later Boyle’s corpuscularianism, and then later Newton’s physics – influence Locke’s thinking on a variety of topics. The result is an impressive account of the history of science at a critical point in its development through the lens of one of the great philosophers of that time. (shrink)

Background. A growing interest in discursive nature of Nobel lectures resulted in a number of studies which emphasize their rhetorical force to influence public opinion and to popularize ideas in different spheres of human life. Analyzing Literature Laureates’ lectures, most researchers focus on linguistic means and the personality of the Nobelist himself/herself. However, characteristics of a writer proper have not been dealt with indepth. This article maintains our previous study, which indicates a close relationship between the content component of the (...) Nobel lecture and the laureate’ outlook; the lecture itself can be regarded as a brief but extremely powerful expression of his/her human and professional qualities. -/- Purpose. The aim of this paper is to examine how literature laureates interpret the notion of a writer in their Nobel lectures and to identify main common themes in creating this collective image. -/- Methods. A method of linguistic description and observation, a descriptive method, and a contextual-interpretation method were employed to analyse the sample of 17 Nobel lectures. -/- Results. The outcomes of our study indicate that Nobel lectures are extremely powerful expression of prizewinners’ human and professional qualities. We have devised a set of five themes, namely the writer’s social duty, his/her destiny, literary background, tools, and literary outcome to describe the collective image of a writer. Within the framework of our research, literary background falls into two subthemes (literary heritage and a personal writing process); discussing the writer’s toolkit, we focus on language and words. -/- Discussion. Our findings show that laureates develop the concept “writer” to varying degrees but all of them stress a direct interconnection between an active social position and the writer’s destiny. Further research can involve the in-depth study of a definite Nobel lecture in terms of the compositional structure and employed linguistic means. (shrink)

Critical notice of Images of Science by P. M. Churchland and C. A. Hooker.

Just as it’s possible to understand novel sentences without having heard them before, it’s possible to understand novel pictures without having seen them before. But these possibilities are often supposed to have totally different explanations: whereas the ability to understand novel sentences is supposed to be explained by tacit knowledge of a compositional theory of meaning for their language, the ability to understand novel pictures is supposed to be explained differently. In this paper I argue against this disanalogy: insofar as (...) the ability to understand novel sentences is explained by tacit knowledge of a compositional theory, I argue, so is the ability to understand novel pictures.

We are told by philosophers that photographs are a distinct category of image because the photographic process is mind-independent. Furthermore, that the experience of viewing a photograph has a special status, justified by a viewer’s knowledge that the photographic process is mind-independent. Versions of these ideas are central to discussions of photography in both the philosophy of art and epistemology and have far-reaching implications for science, forensics and documentary journalism. Mind-independence (sometimes ‘belief independence’) is a term employed to highlight (...) what is important in the idea that photographs can be produced naturally, mechanically, accidentally or automatically. Insofar as the process is physical, natural, mechanical or causal it can occur without human agency or intervention, entirely in the absence of intentional states. Presented innocuously, the idea is that although photographs are dependent on natural or mechanical processes, they can be produced independently of human agency – particularly human beliefs. Presented in a stronger form, the claim is that even if human agency is heavily involved in the production process, the definitive features that make the photograph a photograph and determine its salient properties are nonetheless independent of human minds. In epistemic debates, mind-independence is viewed as essential for explaining why photographs occupy a distinct category among images and justifying a variety of claims about their privileged epistemic and affective status in science, forensics, popular culture and journalism. But, in the philosophy of art, claims about mind-. (shrink)

[Pre-peer review draft available to download.] Our imaginative capacities shape the making of images, while the making of images has the ability to shape our imaginative capacities. What are the connections between vision and mental visual images that allow for this traffic between the contents of our minds and external images? And how are image-makers able to exploit the distinctive powers of imagery, to extend the modes of representation that are available to us, and hence also to extend the (...) resources upon which our imaginations can draw? The chapter explores various aspects of those issues. It starts by exploring “visual imagery” as a general category; and it identifies one very striking range of cases that encompasses both suitable mental and nonmental visual images. It develops a philosophical account of what is distinctive about the range of visual images thus identified. Subsequent sections then use the resulting ideas to investigate some of the ways in which various strategies for creating visual images exploit in remarkably inventive ways possibilities that are latent within the general phenomenon of imagistic representation.

Formal systems are standardly envisaged in terms of a grammar specifying well-formed formulae together with a set of axioms and rules. Derivations are ordered lists of formulae each of which is either an axiom or is generated from earlier items on the list by means of the rules of the system; the theorems of a formal system are simply those formulae for which there are derivations. Here we outline a set of alternative and explicitly visual ways of envisaging and analyzing (...) at least simple formal systems using fractal patterns of infinite depth. Progressively deeper dimensions of such a fractal can be used to map increasingly complex wffs or increasingly complex 'value spaces', with tautologies, contradictions, and various forms of contingency coded in terms of color. This and related approaches, it turns out, offer not only visually immediate and geometrically intriguing representations of formal systems as a whole but also promising formal links (1) between standard systems and classical patterns in fractal geometry, (2) between quite different kinds of value spaces in classical and infinite-valued logics, and (3) between cellular automata and logic. It is hoped that pattern analysis of this kind may open possibilities for a geometrical approach to further questions within logic and metalogic. (shrink)

Objectification involves treating someone as a thing. The role of images in perpetuating objectification has been discussed by feminist philosophers. However, the precise effect that images have on an individual's visual system is seldom explored. Kathleen Stock’s work is an exception—she describes certain images of women as causing viewers to develop an objectifying ‘gestalt’ which is then projected onto real-life women. However, she doesn’t specify the level of visual processing at which objectification occurs. In this paper, I propose that images (...) can affect a viewer's early visual system. I will argue that if a viewer is exposed to a lot of images that depict women as sexual objects, this will bias their early visual selection mechanisms in a way that can result in an objectifying way of seeing. This is an important contribution to work on objectification as it incorporates empirical studies on vision and findings from philosophy of mind. It also examines some of the epistemic and moral consequences of objectification occurring at this early visual stage. (shrink)

Interoperability across data sets is a key challenge for quantitative histopathological imaging. There is a need for an ontology that can support effective merging of pathological image data with associated clinical and demographic data. To foster organized, cross-disciplinary, information-driven collaborations in the pathological imaging field, we propose to develop an ontology to represent imaging data and methods used in pathological imaging and analysis, and call it Quantitative Histopathological Imaging Ontology – QHIO. We apply QHIO to breast cancer hot-spot detection (...) with the goal of enhancing reliability of detection by promoting the sharing of data between image analysts. (shrink)

Enacting Images is devoted to images as they can mobilize cognition and theorizing. Though we can speak of a pictorial turn now that images have become a distinct and full-fledged topic of investigation, some may continue to cling to the impression that images should still be considered within a fundamentally representationalist framework. As an alternative, the enactive approach provides a conceptual setup within which images, beyond their informational, immersive, and aesthetic power, can be considered as being the manifestations of a (...) new epistemic access to the world. The present volume is a collection of essays that reflectively investigate the theoretical prerequisites, scope, and limits of enactive approach. (shrink)
