摘要： 通过一种签名笔迹的频谱分析方法,并提取签名笔迹的压力、速度等动态特征数据,利用傅立叶变换原理,对特征数据进行频谱分析。实验研究发现,同一人的签名笔迹频谱图相似度高,且明显区别于他人的签名笔迹。签名笔迹的频谱分析方法可以直观、有效的鉴别签名笔迹。

关键词: 笔迹, 签名, 频谱分析

Abstract: A spectrum analysis method of signature handwriting was presented. After acquisition of the data of pen pressure and speed, Fourier transform was performed and spectrum of handwriting was calculated. The results show that the spectrums of the same writer’s signatures have high similarity, and clearly distinguish from other’s signatures. The spectrum analysis is a visual and effective method to identify signatures.

Key words: handwriting, signature, spectrum analysis
