Surface Perception from Local Analysis of Texture and Contour.

Abstract

The visual analysis of surface shape from texture and surface contour is treated within a computational framework. The aim of this study is to determine valid constraints that are sufficient to allow surface orientation and distance (up to a multiplicative constant) to be computed from the image of surface texture and of surface contours. The report is in three parts. Part I consists of a review of major theories of surface perception, a discussion of vision as computation and of the nature in which three-dimensional information is manifest in the image, and a study of the representation of local surface orientation. Part II reconisiders the familiar 'texture gradient'. Part III examines our preception of surface contours. It is shown that surface contours are strong sources of information about local surface shape.
