基于笔画系数变换的手写汉字笔迹鉴定
Chinese Handwriting Character Computer Writer Identification Based on Coefficient Transform of Stroke
【摘要】 本研究以手写汉字的基本笔画为对象,确定反映书写特征的相对幅度和相对斜率为时域特征,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5种基本笔画,进行笔迹鉴定的实验,实验取得了满意的结果。
【Abstract】 The research defined the relative altitude and slope 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 and makes the real coefficient as the feature space.The experiment based on the 5 basic strokes which extracted from the 70 Chinese characters of 10 writers.The re-search makes a satisfied result.
