Shape Representation in a Mainpart/Subpart Hierarchy

Not Accessible

Your library or personal account may give you access

Abstract

In many applications, objects may be defined and recognized by shape features. To achieve a measure of generality, a shape recognition system must recognize objects despite changes in position, scale, and orientation of the object, have a notion of similarity of objects, and handle occlusion and the presence of multiple objects. We limit the problem here to the case of single, 2-D, unoccluded objects.
