Abstract

Visual object recognition requires the matching of an image with a set of models stored in memory. In this paper we propose an approach to recognition in which a 3D object is represented by the linear combination of 2D images of the object. We show that this approach handles correctly rigid 3D transformations of objects with sharp as well as smooth boundaries, and can handle some non-rigid transformations. We also suggest how this linear combination property may be used in the recognition process.
