Surface Perception from Local Analysis of Texture and Contour
Kent A. Stevens · DSpace@MIT (Massachusetts Institute of Technology) · 1980
The visual analysis of surface shape from texttire 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 nattire in which three-dimensional information is manifest in the image, and a study of the representation of local surface orientation. A polar form of representation is proposed which makes explicit surface tilt ("which way") and surface slant ("how much").
