消除手写汉字的毛刺及毛刺粘连

Eliminate Glitch and Glitch Join in Handwriting Chinese Characters

在手写汉字中，毛刺是常见的噪声之一，笔划间的毛刺还经常出现粘连现象，这些粘连严重影响了基于轮廓和骨架的特征提取，从而影响手写汉字的识别率。该文通过定义边缘端点、边缘歧点和边缘直角点，提出了一种迭代算法消除毛刺以及毛刺粘连。实验表明，该算法是稳定的。

Glitch is a common kind of noise in handwriting Chinese characters. Glitches between strokes always join together, which can seriously affect those features extracted from contour and skeleton,thus affecting the recognition rate. Based on the definitions of edge end point, edge fork point and rectangular edge point,an iterative algorithm is proposed to eliminate glitches and glitch joins in handwriting Chinese characters in this paper. Experiments show that the algorithm is stable and effective.
