摘要
分析了计算机笔迹鉴别技术的基本过程,对笔迹图像预处理的几个步骤,去噪、二值化、归一化和细化方法进行了分析和研究,其中重点介绍了领域加权平均的去噪方法,给出了基于数学形态学的笔迹细化方法。
The paper analysis and study the basic process of computer handwriting identification technology,mainly the processes of handwriting pre-identification： including de-noising,binarization,normalization and thinned.Mainly concentrate in the methods of de-noising in the process of neighborhood weighted average,the methods of handwriting thinned which based on the mathematical morphology.
