Surface partial matching and application to archaeology

Abstract

Partial matching is a fundamental problem in shape analysis, a field that is recently gaining an increasing importance in computer graphics. This paper proposes anovel approach toperforming partialmatching of surfaces. Given two surfacesMA andMB , our goal is tofind thebestmatch toMA withinMB . The key idea of our approach is to integrate feature-point similarity and segment similarity. Specifically, we introduce a probabilistic framework in which the segmentation and the correspondences of neighboring feature points allow us to enhance or moderate our certainty of a feature-point similarity. The utility of our algorithm is demonstrated in the domain of archaeology, where digital archiving is becoming ever more widespread. In this domain, automatic matching can serve as a worthy alternative to the expensive and time-consuming manual procedure that is used today. & 2010 Elsevier Ltd. All rights reserved.
