基于Hausdorff距离的签字验证问题

Signature Verification Using Hausdorff Distance

签字验证是一种验证身份的重要方法,有着广泛的重要应用。Hausdorff距离是一种常用的距离度量,简单易行并且有效,研究了Hausdorff距离在汉字签字验证问题中的应用,同时研究了签字预处理过程中的角度矫正和汉字切分问题,在85人的签字数据上做了实验,识别率达到90%以上。

The signature verification is an important method for personal identification. Hausdorff distance is a frequently used distance measure because of its easiness to implement and effectiveness. In this paper the application of Hausdorff distance in signature verification is studied, together with signature preprocessing issues such as angle rectification and character division. Experiments on signatures from 85 volunteers have been done. The results are very satisfactory, and prove the practicability of this method.
