摘要
利用模板重复对字符点阵数据累加 ,然后对模板累加数据进行分析 ,提出标定每一像素点的方法 ,根据每个像素点的这些标定信息可确定细化后保留点和细化剔除点 ,进而进行保形的笔画细化 .该方法的最大特点就是笔画细化保形效果好 ,细化结果受笔画边缘毛刺影响很小 .通过上机验证 ,证实该方法是一个在笔画细化上有效实用的方法 .
Value of pixels in character images are accumulated with the 3×3 template. All lines of the accumulation data are scanned on four directions of horizontal, vertical, 45 degree and 135 degree. Based on the change of the pixels′ values, one four dimension vector for per pixels is obtained. The vector is used for marking pixels in strokes. With these information, preserving pixels and removing pixels are determined and stroke thinning is carried out. Advantages of this method are ones that the shape preserving is good and the thinning result is hardly affected by the rough of stroke edges. Results of executing the program on personal computers prove that this method is effective and practical.
