2500个印刷体汉字识别研究
The Investigation of Recognition of 2500 Chinese Characters
-
摘要: 本文提出关于两级汉字识别问题的一种方法.第一级分类采用四种办法:文字边缘长 度,四边编码,交叉线(对角线)编码及文字两侧负象的重心.用这四种办法每类可产生平均 16个字的候选类.第一级分类大大改进了识别效率.第二级分类(识别)利用R变换算法,选 出其中15个分量作为特征,按最小距离分类. 对带有一定干扰的2500个黑体标准汉字样在装有硬盘的DJS-l30机上进行了实验研究, 正确率为98.24%,误识率为0.08%,拒识率为1.68%.Abstract: A two-stage recognition method of Chinese character is proposed in this paper. The experiment has been completed for 2500 standard Chinese characters with noise by means of computer DJS-130. The recognition rate is 98.24%.
