摘　　要：提出一种用于计算机自动识别印鉴的方法,将经过去噪与配准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最大边缘匹配,并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,最后将其用经过训练的第二类势函数进行模式分类。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的要求。A method for Automatic Seal Imprint Identification is presented in this paper. Firstly, the seal imprint matching is divided into some partial regions. According to the furthest edge matching, the similarity degree and the number of different blocks can be obtained to describe the global character of the seal imprint. At last, the second potential function is used to separate the real seals from fake ones. The experiment results demonstrate that the approach performs splendidly in recognition, and can be put into real time use.
