Toward a framework for assembling broken pottery vessels
Stuart J. Andrews, David H. Laidlaw · 2002
This paper addresses how to automatically reconstruct pottery vessels from a collection of sherds using a variety of features and their comparisons. To solve the problem, we designed a computational framework that is founded on the primitive operations of "match" proposal and evaluation. A match defines the geometric relationship between a pair of sherds. This framework affords a natural decomposition of the computation required by an automatic assembly process and provides a concrete basis to evaluate the utility of different features and feature comparisons for assembly. Pairwise matches are proposed and subsequently evaluated by a series of independent feature similarity modules. Assembly strategies are abstracted from the feature-specific sherd details and operate solely in terms of the probabilistic output of pair-wise proposals and evaluations
