摘　　要：本文讨论以提取签名字符的块、孔、段、端点、三叉点、四叉点、五叉点等静态拓扑特征作为签名真伪识别依据的静态识别方法。对8组共计350个签名进行识别实验,实验结果表明识别率在94％以上。当静态识别与动态识别相结合时,识别率为98％。本文还提出了“彻底细化”和提取叉点的两个新算法,效果很好。A topological method for Chinese signature verifications is presented. The method extracts the topological features such as connected sub-graphs, holes, strokes and cross-points etc. from the image of signatures as the basis for recognitions. Based on the method, an automatic Chinese signature verification system is designed and implemented. By testing the system with 350 signatures from 8 groups, the average correct recognition rate is over 94%.
