Correspondence and Affine Shape from Two Orthographic Views: Motion and Recognition

Abstract

The paper presents a simple model for recovering affine shape and correspondence from two orthographic views of a three-dimensional object. The paper has two parts. In the first part it is shown that four corresponding points along two orthographic views, taken under similar illumination conditions, determine affine shape and correspondence for all other points. In the second part it is shown that the scheme is useful for purposes of visual recognition by generating novel views of an object given two model views in full correspondence and four corresponding points between the model views and the novel view. It is also shown that the scheme can handle objects with smooth boundaries, to a good approximation, without introducing any modifications or additional model views....
