Perceiving in Depth

� 2012 by Oxford University Press, Inc. All rights reserved. Volume 2 deals with stereoscopic vision in cats, monkeys and humans. It starts with a review of physiological mechanisms of stereoscopic vision. Stereoscopic vision depends on inputs from the two eyes converging in the visual cortex. The mechanisms of binocular rivalry and of other ways in which binocular images interact are reviewed. The images of objects on the horopter are combined so that corresponding parts are brought into register. Once the images are in register, differences between the images are used to code depth. An account is provided of the nature of these differences, the precision with which they are detected (stereoacuity), and the use to which they are put. Two chapters describe how impressions of depth created by binocular disparity are modified by depth contrast, figure-ground interactions, motion, and attention. The book ends with a review of stereoscopic techniques used to create three-dimensional displays and the practical applications of stereoscopic devices.
