| Abstract: | In accordance with evaluating the coincidence degree of the vector data and graph, this paper develops a method to match the edge of photograph with any vector curve based on generalized Hough transformation. The results of the experiment show that the coincidence degree of the vector data and graph could be evaluated effectively and objectively using the methods described in this paper. |
