| 摘 要： | 数学公式识别是OCR技术的重要组成部分,目前相关的研究还很欠缺。文章在简要介绍数学公式识别发展状况的基础上,针对结构分析这一公式识别的关键环节,提出了一种基于基准线、运算符作用域并结合语法分析数学公式结构的方法。实验表明,该方法对公式结构具有较好的适应性。

| Abstract: | It is an important part to recognize mathematical expressions in OCR technology.At present,the research in this aspect is rare.But it is a crucial course for the analysis of structure in mathematical expressions recognitlon.To this,a method of structural analysis of mathematical expressions which connects of baseline and operator range with syntax analysis is put forward in the printed mathematical expression recognition,based on the introduction of the development state of mathematical expression recognition.In experiments,this method has shown favorable adaptability for the structure of mathematical expressions. |
