摘　　要：提出了一种用于计算机自动识别印鉴的方法。该方法将经预处理的印鉴图像分成若干子区域,通过边缘最大匹配算法找出经过膨胀或腐蚀运算后所能得到的边缘最大程度的匹配,并以此为基础求得区域相似度和差异块个数,用它们描述印鉴图像的总体特征。然后用经过训练的第二类势函数对其进行模式分类。实验结果表明该方法具有很强的识别能力并能够满足实时性要求。A method for Automatic Seal Imprint Verification is presented in this paper. According to the analysis of image difference between real and fake seal, three intrinsic features are extracted. Then the second potential function is used to separate the real seals from fake ones. The experiment results show that this approach has an ideal performance in recognition, and it can be put into practical use.
