Stimulus tokens for stereopsis

Show Summary Details

Preview

Binocular disparities used for stereoscopic vision can be based on any of several stimulus tokens. These tokens include differences in position, orientation, texture, color, temporal phase, or motion. Also, part of an object seen by one eye may not be visible to the other eye, an effect known as monocular occlusion. Stereopsis based on monocular occlusion is known as Da Vinci stereopsis. This chapter deals with the extent to which each of these tokens is used for stereopsis. It also reviews the effect known as Panum’s limited case and discusses whether differences in the positions of images produced by geometrical illusions or chromatic aberration can form the basis for stereopsis.

Keywords: tokens for stereopsis; da Vinci stereopsis; Panum’s limiting case; chromostereopsis
