| 摘 要： | 该文设计并实现了一个联机手写数学公式识别系统。系统通过手写输入符号、字符进行有效的预处理,获取并简化字符笔画区域码序列以及字符位置关系,然后应用模糊矩阵的区域码序列匹配运算进行字符匹配,在匹配过程中提供字符的自学习能力,最后通过基于数学公式规则的语法分析,实现了数学公式的识别。该文的手写数学公式识别系统相对简单,使用方便。

| Abstract: | This paper designed and realized an online handwritten mathematical formula recognition system.The system uses a handwritten interface,first do pretreatment of the input symbols and characters,gain and simplify the character stroke region code sequence as well as the character position relations,then adopt fuzzy matrix area code serials to carry on character matching.During the process of matching,the system provides character learning function and at last use syntax analysis based on math formula regulatio... |
