Abstract: This article elaborates on a method of recovery for torn slivers of rules. The algorithm first transforms the image into the corresponding pixel matrix, and the matrix is processed by two vales. Next, according to the continuity of text strokes, the matching matrix of edge information is calculated, and then the similarity matrix between fragments is calculated according to the continuity between texts. Finally, combining the information of matching degree matrix and similarity matrix, when matching a certain piece, the corresponding next one is highly consistent with the matching degree matrix as well as the similarity matrix, so as to achieve the splicing and restoration of broken paper. The verification of experimental shredding stitching shows that the effect is good, the method is accurate and convenient. It is feasible.
