摘　　要：本文讨论了印鉴鉴别中的图像配准和特征提取问题.预处理后先用动态阈值法对印鉴图像进行分割,再用启发式搜索法进行配准,继而进行特征提取.According to the principle of image analysis and pattern recognition, a segmentation algorithm based on improved entropic method and dynamic threshold, and a registration algorithm which uses heuristic search scheme are proposed in this paper. By the proposed approach, several effective features are extracted and finial decision is made using a statistical classification model with structural information. It is showed the algorithm is accuracy, reliability and compatibility in practical use.
