Objects of Vision by A. Joan Saab Pdf

Advances in technology allow us to see the invisible: fetal heartbeats, seismic activity, cell mutations, virtual space. Yet in an age when experience is so intensely mediated by visual records, the centuries-old realization that knowledge gained through sight is inherently fallible takes on troubling new dimensions. This book considers the ways in which seeing, over time, has become the foundation for knowing (or at least for what we think we know). A. Joan Saab examines the scientific and socially constructed aspects of seeing in order to delineate a genealogy of visuality from the Renaissance to the present, demonstrating that what we see and how we see it are often historically situated and culturally constructed. Through a series of linked case studies that highlight moments of seeming disconnect between seeing and believing—hoaxes, miracles, spirit paintings, manipulated photographs, and holograms, to name just a few—she interrogates the relationship between “visions” and visuality. This focus on the strange and the wonderful in understanding changing notions of visions and visual culture is a compelling entry point into the increasingly urgent topic of technologically enhanced representations of reality. Accessibly written and thoroughly enlightening, Objects of Vision is a concise history of the connections between seeing and knowing that will appeal to students and teachers of visual studies and sensory, social, and cultural history.

Invariant Recognition of Visual Objects by Evgeniy Bart,Jay Hegdé Pdf

This Research Topic will focus on how the visual system recognizes objects regardless of variations in the viewpoint, illumination, retinal size, background, etc. Contributors are encouraged to submit articles describing novel results, models, viewpoints, perspectives and/or methodological innovations relevant to this topic. The issues we wish to cover include, but are not limited to, perceptual invariance under one or more of the following types of image variation: • Object shape • Task • Viewpoint (from the translation and rotation of the object relative to the viewer) • Illumination, shading, and shadows • Degree of occlusion • Retinal size • Color • Surface texture • Visual context, including background clutter and crowding • Object motion (including biological motion). Examples of questions that are particularly interesting in this context include, but are not limited to: • Empirical characterizations of properties of invariance: does invariance always exist? How wide is its range and how strong is the tolerance to viewing conditions within this range? • Invariance in naïve vs. experienced subjects: Is invariance built-in or learned? How can it be learned, under which conditions and how effectively? Is it learned incidentally, or are specific task and reward structures necessary for learning? How is generalizability and transfer of learning related to the generalizability/invariance of perception? • Invariance during inference: Are there conditions (e.g. fast presentation time or otherwise resource-constrained recognition) when invariance breaks? • What are some plausible computational or neural mechanisms by which invariance could be achieved?

Human Perception of Objects by David Regan Pdf

This upper-level textbook begins with the concepts of modern psychophysical vision research (as opposed to vision system physiology), before detailing aspects of the processes that allow us to distinguish objects from their surroundings. The author then forms an integrated model of these processes, drawing on material in earlier chapters. Ten appendices present more advanced material for students with little knowledge of physics or mathematics.

Stereoscopic acuity in ocular pursuit of moving objects by Matthias Sachsenweger,Ulrich Sachsenweger Pdf

There has been growing acceptance of the insight that the methods so far used in the testing of visual functions have been inadequate when it comes to specific problems and should, therefore, be supplemented with more specialised methods for dynamic testing. As long as two decades ago, large-scale mass screening produced evidence to the effect that visual acuity, so far exclusively determined by means of still samples, was not identical with visual acuity in the ocular pursuit of moving targets (dynamic visual acuity). In other words, vision testing can, at present, provide little informa tion on an individual's capability of identification, appreciation, and judge ment of mobile objects. Spatial, three-dimensional perception of moving targets, hereafter re ferred to as dynamic stereoacuity, is the particular subject on which findings are reported in this article. Findings of that kind are of considerable relevance to everyday life, since many of the phenomena that have to be three-dimensionally perceived in private life and in occupational practice, are in movement. So far, dynamic stereoacuity has never been systematical ly studied and is still a blank space on the maps of ophthalmology and physiology. This is equally true for dynamic stereoscopy in binocular vision as well as for perception on the basis of movement parallax, a phenomenon of differentiated contour displacement within a given field of vision which is also available to the monocular individual under conditions of head or body or object movement within the visual space.

Visual Agnosia, second edition by Martha J. Farah Pdf

The cognitive neuroscience of human vision draws on two kinds of evidence: functional imaging of normal subjects and the study of neurological patients with visual disorders. Martha Farah's landmark 1990 book Visual Agnosia presented the first comprehensive analysis of disorders of visual recognition within the framework of cognitive neuroscience, and remains the authoritative work on the subject. This long-awaited second edition provides a reorganized and updated review of the visual agnosias, incorporating the latest research on patients with insights from the functional neuroimaging literature. Visual agnosia refers to a multitude of different disorders and syndromes, fascinating in their own right and valuable for what they can tell us about normal human vision. Some patients cannot recognize faces but can still recognize other objects, while others retain only face recognition. Some see only one object at a time; others can see multiple objects but recognize only one at a time. Some do not consciously perceive the orientation of an object but nevertheless reach for it with perfected oriented grasp; others do not consciously recognize a face as familiar but nevertheless respond to it autonomically. Each disorder is illustrated with a clinical vignette, followed by a thorough review of the case report literature and a discussion of the theoretical implications of the disorder for cognitive neuroscience. The second edition extends the range of disorders covered to include disorders of topographic recognition, and both general and selective disorders of semantic memory, as well as expanded coverage of face recognition impairments. Also included are a discussion of the complementary roles of imaging and patient-based research in cognitive neuroscience, and a final integrative chapter presenting the "big picture" of object recognition as illuminated by agnosia research.
