Paper Abstract

This paper is concerned with recovering qualitative descriptors of three-dimensional surface shape from binocular stereo disparity. In particular the emphasis is on recovering the sign of Gaussian curvature of binocularly projected three-dimensional surface patches (i. e. surface patches that are locally parabolic elliptic or hyperbolic in shape). It is shown that this information can be recovered from patterns in the differential orientation of projected surface detail (e. g. texture). 1.
