Abstract

In this paper, we are presenting a new surface signature-based representation that is orientation-independent and can be used to match surfaces under rigid transformation including uniform scaling. In addition to surface matching, the proposed representation can be used to estimate the scaling factor between the surfaces. The proposed scheme represents the surface signatures as Extended Polar Maps and it will be known as SEPMap scheme. We'll demonstrate the usefulness of the SEPMap scheme by applying it to the problem of recognizing complete and partial 3D models of objects.
