Local fragment reassembly based on edge information

The reassembly of irregular fragments can be divided into content-based reassembly and contour-based reassembly according to the characteristics of fragments. A new method based on contour is proposed to find the real local matching, using the length of edge to be spliced and intensity cross-correlation. Firstly, the contours of the fragments are extracted and the corner points are detected. By calculating the edge length of fragments, the intensity cross-correlations of two fragments with equal edge length are calculated. The real matching is determined by comparison. Simulation results show that the new method is simple and effective.
