A review of how images are brought into binocular register is followed by a review of stimulus tokens used to detect disparities. Cyclopean effects, such as cyclopean illusions, cyclopean motion, texture segregation, and binocular direction are reviewed. Factors that influence stereoacuity are discussed. Two chapters describe how stimuli in distinct depth planes produce contrast effects, and affect motion perception and whiteness perception. The Pulfrich stereomotion effect and perception of motion in depth are reviewed. The volume ends with a review of applications of stereoscopy.

Download or read book The Roots of Visual Awareness written by C.A. Heywood and published by Elsevier. This book was released on 2003-10-31 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume was assembled in honor of Professor Alan Cowey FRS, and attempts to embrace his wide range of research interests in visual neuroscience. It is divided into four sections. The first contains a group of papers dealing with different fundamental aspects of the visual system, including the control and monitoring of eye movements. The second is concerned with the functional organization of cortical visual areas and their role in visual perception and visually guided action. The third addresses issues concerning color and motion perception, along with broader questions of visual attention; and the effects of selective brain damage on these different aspects of visual experience. The fourth and final section of the volume deals explicitly with questions relating to visual awareness, with particular emphasis on 'blindsight', a topic on which Alan Cowey has worked extensively in recent years, both in humans and in monkeys.

Download or read book Perceiving in Depth Volume 2 Stereoscopic Vision written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.

Download or read book The Neuropsychology of Vision written by Manfred Fahle and published by Oxford University Press. This book was released on 2003-10-30 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neuropsychology of Vision describes a range of new approaches to neuropsychological investigation and provides a broad overview of visual neuropsychology. The book starts by presenting the results from new research employing single-unit recordings, on the neuronal basis of perception demonstrating that the visual system relies strongly on feedback from higher to lower levels of information processing, and that neuronal plasticity exists in the primary sensory cortices of adults, areas previously considered to be hard-wired. The book also describes other new and adapted techniques to measure brain activity, including multi-unit sum potential recording, functional magnetic resonance imaging and employing transcranial magnetic stimulation to induce temporary, circumscribed functional lesions in the cortices of normal subjects to mimic disorders. The coverage then moves on to review the experience of patients suffering from disturbances of visual perception. The disorders covered include agnosia, neglect, blindsight and achromatopsia. The final chapter is devoted to recovery and rehabilitation from cerebral visual disorder. Professors Fahle and Greenlee have brought together some of the leading international specialists in the field to provide this comprehensive and up-to-date review.

Download or read book Using Noise to Characterize Vision written by Rémy Allard and published by Frontiers Media SA. This book was released on 2016-03-02 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise has been widely used to investigate the processing properties of various visual functions (e.g. detection, discrimination, attention, perceptual learning, averaging, crowding, face recognition), in various populations (e.g. older adults, amblyopes, migrainers, dyslexic children), using noise along various dimensions (e.g. pixel noise, orientation jitter, contrast jitter). The reason to use external noise is generally not to characterize visual processing in external noise per se, but rather to reveal how vision works in ordinary conditions when performance is limited by our intrinsic noise rather than externally added noise. For instance, reverse correlation aims at identifying the relevant information to perform a given task in noiseless conditions and measuring contrast thresholds in various noise levels can be used to understand the impact of intrinsic noise that limits sensitivity to noiseless stimuli. Why use noise? Since Fechner named it, psychophysics has always emphasized the systematic investigation of conditions that break vision. External noise raises threshold hugely and selectively. In hearing, Fletcher used noise in his famous critical-band experiments to reveal frequency-selective channels in hearing. Critical bands have been found in vision too. More generally, the big reliable effects of noise give important clues to how the system works. And simple models have been proposed to account for the effects of visual noise. As noise has been more widely used, questions have been raised about the simplifying assumptions that link the processing properties in noiseless conditions to measurements in external noise. For instance, it is usually assumed that the processing strategy (or mechanism) used to perform a task and its processing properties (e.g. filter tuning) are unaffected by the addition of external noise. Some have suggested that the processing properties could change with the addition of external noise (e.g. change in filter tuning or more lateral masking in noise), which would need to be considered before drawing conclusions about the processing properties in noiseless condition. Others have suggested that different processing properties (or mechanisms) could be solicited in low and high noise conditions, complicating the characterization of processing properties in noiseless condition based on processing properties identified in noise conditions. The current Research Topic probes further into what the effects of visual noise tell us about vision in ordinary conditions. Our Editorial gives an overview of the articles in this special issue.
