Abstract:

This study built up a signatures dataset and imported signatures on paper into the computer. By extracting and analyzing the dynamic data of strokes)width, grayscale and radian of signatures, the regularities of these dynamic data were studied and an effective method to distinguish original signatures from forgery ones was found out.

Key words: static, signature, width, grayscale, radian

摘要：

通过实验建立签名笔迹样本库，导入计算机后，提取签名笔迹的宽度、灰度和弧度等动态特征数据，研究这些动 态特征的规律，找到一种有效的鉴别本人签名和非本人签名的方法。

关键词: 签名笔迹, 动态特征, 宽度, 灰度, 弧度
