在印鉴识别中的配准方法

Registration Method of Seal Imprint Identification

提出了在中文印鉴识别中两幅印鉴图象的配准方法．它包括对印鉴图象的预处理，该方法在保留图象边缘的同时对图象进行了平滑处理，利用聚类算法提取标准和待识别印鉴的特征点集，依据最小均方差变换实现两个点模式的匹配．通过实验获得了两幅印鉴图象的高精度配准结果．

Seal identification serves the same function as signature identification.In this paper, a registration method of two seal imprints in the Chinese seal identification is proposed. It includes the preprocess of seal imprint image, which not only preserves the image edges but also smoothes the image itself, and the abstraction of feature point set of the standard and identified seal imprints by cluster algorithm, and matching two point patterns by a minimum square error transform. The registration results of high precision are obtained by the experiment.
