Abstract

Publisher Summary This chapter presents contributions to the explanation of stereoscopic depth perception from a psychophysical, neurophysiological, and computational point of view. The chapter discusses these contributions in relation to the underlying issues raised by the study of stereoscopic vision. It presents a sketch of older theories on stereoscopic depth perception and develops a general description of the major information processing problems that the visual system has to solve when calculating spatial depth based on retinal disparity values. Any theory of stereoscopic depth perception has to consider these general constraints. The chapter also presents an influential recent model of the foundations of stereoscopic depth perception developed by David Marr and discusses some problems and extensions of Marr's model. The chapter presents an alternative conception of stereoscopic vision: Grossberg's theory attempts to explain binocular depth perception within the context of a comprehensive model of human visual information processing.
