本程序采用的算法有两部分组成：一是建立各类字符的模型库，二是对待识别样本进行识别分类。但由于本程序采用的七个特征量不能完全识别出ABCDE五个字母，其中C会被识别为A，B会被识别为D，这可能是因为通过七个特征量进行识别是A与C、B与D的计算值比较接近，故从而无法正确识别，该算法有待改进。-Algorithm used in this procedure has two parts: First, the establishment of various types of character model library, and the other is to treat samples for identification to identify categories. However, due to the procedures used by seven features ABCDE can not be fully identified the five letters, of which C will be identified as A, B will be identified as D, this may be due to the adoption of the seven features to identify the A and C, B and D close to the calculated value, it thus can not correctly identify the algorithm to be desired.
