Solving archaeological puzzles

This paper focuses on the re-assembly of an archaeological artifact, given images its fragments. problem can be considered as a special challenging case puzzle solving. The restricted natural image from square pieces has been investigated extensively and was shown to difficult in own right. Likewise, matching “clean” 2D polygons/splines based solely their geometric properties studied. But what if these ideal conditions do not hold? is addressed paper. Three unique characteristics fragments make solving extremely difficult: (1) are general shape; (2) They abraded, especially at boundaries (where strongest cues for should exist); (3) domain valid transformations between continuous. key contribution this fully-automatic algorithm that addresses intriguing domain. We show our approach manages correctly reassemble dozens broken artifacts frescoes.
