Shape And Correspondence
Su-shing Chen, Michael A. Penna · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
An important problem in computer vision and image understanding is how to establish a correspondence between points in multiple images of an object. In this paper we illustrate how shape can be used in establishing point correspondences for objects bounded by smooth surfaces. This approach uses local geometric surface features in 3-dimensional world space as opposed to features in the intensity space of an image, as is done elsewhere in the image understanding literature.
