基于笔压变换系数的手写汉字笔迹鉴定

Chinese Handwriting Character Computer Writer Identification Based on Coefficient Transform of Pressure Change

本研究以手写汉字的基本笔划为对象,确定反映书写特征的笔压为时域特征,并对时域特征进行Fourier变换,抽取变换实系数形成特征空间,实现笔迹鉴定。本研究采用10位书写者,各书写70个汉字,提取4种基本笔划的笔压特征,进行笔迹鉴定的实验,取得了满意的实验结果。

The research defined the pressure reflecting the write feature as the time space feature based on the basic stroke of handwriting Chinese characters. The paper makes the Fourier for time space feature of pressure and makes the real coefficient as the feature space. The experiment based on the pressure feature of 4 basic strokes which extracted from the 70 Chinese characters of 10 writers. The research makes a satisfied result.
