AN INVESTIGATION OF TECHNIQUES FOR ASYMMETRY RECTIFICATION

This paper is concerned with symmetry and asymmetry in objects. Earlie r studies on the subject have dealt with the detection of symmetry. We study the problem of asymmetry rectification, i.e., given an asymmetr ic profile suggest geometric changes to make it symmetric. We have inv estigated two techniques for asymmetry rectification. This paper repor ts on the techniques and the results. First, we analyze the problem us ing skeleton representations and propose a simple algorithm for rectif ying asymmetric convex profiles. Next, we outline an optimization sche me for the rectification of convex and nonconvex profiles, in 2D and 3 D. Implemented examples are presented for both algorithms.
