title: Stereovision: beyond disparity computations.
abstract: One of the most powerful sources of information about three-dimensional (3-D) structure is provided by stereovision (or stereopsis). For over a century, theoretical and empirical investigations into this ability have focused on the role of binocular disparity in generating percepts of 3-D structure. Recent work in image segmentation demonstrates that stereovision can cause large changes in perceptual organization that cannot be understood on the basis of binocular disparity alone. It is argued that these phenomena reveal the need for theoretical tools beyond those that have dominated the study of visual perception over the past three decades.
