Abstract: ABSTRACT A long-standing challenge to understanding the human visual system is to reconcile our unified visual experience of a three-dimensional (3D) world with findings suggesting that the visual system operates, at least partially, as a modular system. This dissertation is composed of studies that investigate how systematic changes in retinal image structure, and changes in binocular disparity arising from either motion in depth or rotation in depth, are used to derive a number of perceptual judgments in 3D space. The assumption that looming and stereomotion mechanisms operate in tandem, and feed into an early joint motion-in-depth mechanism, is challenged by the findings of Chapter 3. Using the flash-lag paradigm, it was found that stereomotion, but not looming, induces an apparent displacement in the position in depth of a flashed object, and the effect is speed dependent. This finding suggests that, in terms of the encoding of metric depth, the two mechanisms produce qualitatively different results. Moreover, the flash-lag-in-depth phenomenon is accompanied by a novel size effect, which appears to contradict the geometrical predictions typically used to account for size illusions associated with depth perception, and serves as an evidence of top-down processing in deriving congruent estimates of image size and position in depth. Assuming that different mechanisms underlie the computations of 2D motion and motion in the depth, their outputs must be combined at some stage, given that objects in the 3D world often traverse frontoparallel and median planes simultaneously. Findings of how 2D motion affects the apparent speed of motion in depth are reported in Chapter 4. Dots defining a frontoparallel square conducted random walks on its surface, while the square itself moved towards the observer. It was found that apparent speed in depth increases as a function of the speed of random 2D motion. Additionally, the visual system appears to combine motion signals in the twoplanes by vector summation when motion in depth is defined by stereomotion, whereas averaging is implemented when motion in depth is defined by looming. The detection of 3D structure often requires the integration of local motion signals traversing 3D space. An investigation of this process, using cylinders with an apparently identical 3D shape, is reported in Chapter 5. A cooperative integration of disparity and structure from motion was found: compared to bi-rotation in depth, a unified direction of rotation in depth improves detection performance, which can be explained by the functional properties of MT neurons. While the apparent 3D shape of cylinders remains constant for a range of dot densities, sensitivity to the existence of cylinders embedded in random noise increases as a function of dot density, which implies a gradation in 3D-structure interpolation. To examine the effect of apparent orientation in 3D space imposed on the bi-stable appearance of rotation in depth, in Chapter 6 the detection of spontaneous and physical reversals in the direction of motion were compared for cylinders and Necker cubes defined by structure from motion. The frequency of spontaneous reversals occurring with the Necker cube is far lower than with the cylinder and with Necker cubes defined by outlines. Furthermore, physical reversals that occurred with the Necker cube are much more detectable than with the cyli

Download or read book Vision Science written by Stephen E. Palmer and published by MIT Press. This book was released on 1999-04-14 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book revolutionizes how vision can be taught to undergraduate and graduate students in cognitive science, psychology, and optometry. It is the first comprehensive textbook on vision to reflect the integrated computational approach of modern research scientists. This new interdisciplinary approach, called "vision science," integrates psychological, computational, and neuroscientific perspectives. The book covers all major topics related to vision, from early neural processing of image structure in the retina to high-level visual attention, memory, imagery, and awareness. The presentation throughout is theoretically sophisticated yet requires minimal knowledge of mathematics. There is also an extensive glossary, as well as appendices on psychophysical methods, connectionist modeling, and color technology. The book will serve not only as a comprehensive textbook on vision, but also as a valuable reference for researchers in cognitive science, psychology, neuroscience, computer science, optometry, and philosophy.

Available in PDF, EPUB and Kindle. Book excerpt: The field of computer vision combines techniques from physics, mathematics, psychology, artificial intelligence, and computer science to examine how machines might construct meaningful descriptions of their surrounding environment. The editors of this volume, prominent researchers and leaders of the SRI International AI Center Perception Group, have selected sixty papers, most published since 1980, with the viewpoint that computer vision is concerned with solving seven basic problems: Reconstructing 3D scenes from 2D images Decomposing images into their component parts Recognizing and assigning labels to scene objects Deducing and describing relations among scene objects Determining the nature of computer architectures that can support the visual function Representing abstractions in the world of computer memory Matching stored descriptions to image representation Each chapter of this volume addresses one of these problems through an introductory discussion, which identifies major ideas and summarizes approaches, and through reprints of key research papers. Two appendices on crucial assumptions in image interpretation and on parallel architectures for vision applications, a glossary of technical terms, and a comprehensive bibliography and index complete the volume.

Everything we perceive comes in delightful multicolored forms. Now, in the age of science, we want to comprehend what and why we see. Two dozen outstanding biologists, chemists, physicists, psychologists, computer scientists and mathematicians met at the Institut d'Hautes Etudes Scientifiques in Bures-sur-Yvette, France. They expounded their views on the physical, biological and physiological mechanisms creating the tapestry of patterns we see in molecules, plants, insects, seashells, and even the human brain. This volume comprises surveys of different aspects of pattern formation and recognition, and is aimed at the scientifically minded reader.
