Interactively Rejioning 2D Oracle Bone Fragments Based on Contour Matching

The oracle bone fragments are usually rejoined manually by experts. This is a very challenging task because of the huge number of fragments and the complexity of the breakage situation, which leads to low efficiency of manual search and low accuracy of results. In this paper, we explore a computer-aided technology in 2D oracle rubbings rejoining to accelerate the matching and searching process. We provide an oracle rejoining pipeline and interactive interfaces to integrate contour extraction, matching, searching, and merging of fragments. Besides, we conduct experiments on a real oracle bone dataset, and the results demonstrate that our technology finds the correct matching fragments within a certain rank and achieves satisfactory final matching results.
