摘　　要：本文分析了几种印鉴鉴别方法的优缺点 ,并提出了一种基于环投影模板匹配的印鉴鉴别方法。该方法先将印鉴图像分成若干个区域环 ,提取反映印鉴本质特征的参数形成局部和全局特征。然后利用一维模板匹配法分别对印鉴边框和印鉴边框内部字信息进行鉴别。实验结果证明 。In this paper,the advantage and disadvantage of several seal imprint recognition method have been compared,and an approach for seal imprint recognition based on ring projecting template matching is proposed.Firstly,the seal imprint is divided into some rings,and the local and global intrinsic features are extracted.Then the recognition is made,with the rim and the words of seal imprint separated,by 1 D template matching.The experimental results show that the proposed approach is of adaptability and reliability.
