摘要
该文讨论了设计一个实时手写数学公式识别系统时需要解决的主要问题。系统通过手写输入接口及输入笔划组合软件,进行符号、字符识别及图形语法分析,产生与输入相对应的语法分析树,并由此转换成诸如Latex、数学的或LISP-like符号等输出形式,与基于特殊方程描述语言的识别系统相比,该文的手写数学公式识别系统相对简单,使用方便。
This paper discusses the main problems of designing an on-line handwritten mathematical formula recognition system.The system uses a handwritten interface,the stroke grouping software and a graph grammar to generate an internal phrase tree of the input,which can be converted into output representations such as LATEX,Mathematical ones,or LISP-like ones.The designed equation editor is simple and more convenient than systems based on specialized languages.
