Depth contrast

Show Summary Details

Preview

An object in one location can influence the perceived 3-D spatial disposition of an object in a neighboring location or of an object seen successively in the same location. These effects come under the heading of depth contrast. This chapter discusses types of local and global depth contrast between lines and surfaces. It also discusses physiological processes responsible for depth contrast, and theoretical models of these processes. The chapter ends with a discussion of depth contrast produced by deformation disparities, namely size disparities, shear disparities, and by combinations of horizontal and vertical disparities.

Keywords: depth contrast; successive contrast; deformation disparities
