Research on key technologies of the computer aided rejoining of Oracle Bone Inscriptions

The rejoining of oracle bone inscription is an important process of oracle bone arrangement. In this paper, we proposed the algorithms for contour information extracting and tracking from these shell images and vector extracting algorithms of the feature of the contour fragments. We proposed the technical route and implementation method of establishing oracle shell images database, and developed a computer aided system of Oracle Bone Inscriptions Rejoining based on the contour matching technology. After a being rejoined shell is selected, this system can automatically find a dynamic database for the possible target shells. Based on which, the experts can carry out shell intelligent rejoining by knowledge of oracle bone inscription.
