摘 要:文介绍了一个联机中文签名鉴定系统。系统将联机输入的签名切分为笔段,以笔段作为签名的特征区域,采用动态规划方法寻求持测签名和参考签名笔段之间的最优对应关系,根据最优对应关系,再利用区域相关算法计算待测签名和参考签名之间总的匹配距离。在对680个测试签名样本的识别实验中,平均正确识别率达到92.8%,初步显示了本系统的可行性。This paper presents an on-line signature verification system.The signature is segmented into strings. The strings are regarded as the feature reglons. Afer string segmentation, accouling to some relahvely simple static features, the dynamic programming method is used to find out the opimal corresponding relation betWeen the strings of the test signature and the reference signature. Accouling to the optimal corresponding relation, the regional correlation algorithm is further used to compute the total matching distance between the test signature and the reference signature, taking both the static and the dynamic features into account. For a test data set of 680 signatUr samples, average correct recognition rate of 92.8% is obtained. The experiment results reveal the feasibility of the proposed system.
