Fragment Splicing Method Based on Surface Texture Characteristic
In the process of restoration of ceramic artifacts, the fractured site is easy to be damaged due to its own characteristics, the environment, and man-made factors. The traditional stitching method based on geometric information of fracture location has some limitations. We propose a method of splicing of fractured sites combined with surface texture and boundary contour for the restoration of fragments of ceramic artifacts. Firstly, the potential ridge points are determined by the curvature and the least squares method is used to extract the texture features of the debris surface. Then, the texture elements are combined with the edge length and the vertex angle information to construct damaged texture constraints and realize preliminary matching. Two adjacent points in the boundary set of the contours are concatenated to form the contour chord sequence descriptor, and the contour position information is constrained to obtain the final matching pair. The results show that the proposed algorithm can achieve the splicing of broken artifact fragments, and it has certain advantages for the debris with obvious texture features.
