Depth Perception Through Motion


Book Description

Series in Cognition and Perception: Depth Perception Through Motion focuses on the processes, methodologies, and techniques involved in depth perception through motion, including optic array, rigid motions, illusions, and axis. The book first elaborates on the paradox of depth perception, illusions of motion in depth, and optic array. Discussions focus on rigid motions in three-dimensional space, perspective gradients, projection plane, stereokinetic effect, rotating trapezoid, and the windmill and fan illusions. The text then examines transformations leading to the perception of depth, slant perception, and perceived direction of rotary motion. Topics include shadow and computer projections, direct observation of rotating figures, a model of the perception of rotary motion, dynamic slant and static slant perception, translations along the Z axis, and rotations about the X or Y axis. The publication is intended for researchers and graduate students interested in depth perception in dynamic environments.




Perceiving in Depth, Volume 2


Book Description

Volume 2 addresses stereoscopic vision. It starts with the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, and interocular transfer. 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.

Perceiving in Depth, Volume 1


Book Description

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 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.




Perceiving in Depth, Volume 3


Book Description

Volume 3 addresses depth-perception mechanisms other than stereopsis. It starts by reviewing monocular cues to depth, including accommodation, vergence, perspective, interposition, shading, and motion parallax. Constancies, such as the ability to perceive the sizes and shapes of objects as they move are reviewed. The ways in which different depth cues interact are discussed. One chapter reviews information used to perceive motion in depth. Pathologies of depth perception, including stereoanomalies and albanism are reviewed. Visual depth-perception mechanisms through the animal kingdom are reviewed together with a discussion of the evolution of stereoscopic vision. The next chapter describes how visual depth perception guides movements of the hand and body. The next three chapters review non-visual mechanisms of depth perception, including auditory localization, echolocation in bats and marine mammals, the lateral-line system of fish, electrolocation, and heat-sensitive sense organs. The volume ends with a discussion of mechanisms used by animals to navigate.




Celebrating the Usefulness of Pictorial Information in Visual Perception


Book Description

This book is a collection of biographical essays describing the influence of Julian Hochberg, a leading researcher in vision science and human performance modeling. In this chapter, Jeremy Beer, who was Hochberg's doctoral student, describes three areas in which Hochberg's experimental approach remains influential in vision research. The first area comprises the comparison of motion information versus pictorial depth cues (e.g., linear perspective, relative size) in moving viewers' perception of distance and slant. Hochberg demonstrated that pictorial cues can overcome other sources of information to determine how viewers will perceive a three-dimensional scene. These principles continue in the design of modern cockpit displays incorporating features like "highway in the sky." The second area comprises the comparison of motion information versus pictorial cues in the perception of time-to-collision. As in the first topic, recent work has demonstrated that pictorial cues can dominate other kinds of information in important visually controlled tasks such as vehicle braking and interceptive action. The third area comprises the effects of display boundaries on the perception of extended scenes. Recent work in this field has determined that human operators perceive scenes according to a distorted geometry when the boundaries of the display are restricted. (3 figures, 13 refs.).
