基于递归策略的数学公式识别模型

Discussion on the Mathematical Formula Recognition Model Based on Recursion Strategy

在简要介绍数学公式识别发展状况的基础上,提出了一个基于递归策略的数学公式识别模型。该模型由版面分析和数学公式结构表达两部分组成。版面分析主要是提取文档中的数学公式;数学公式结构的表达采用一种递归算法将公式用结构树表示,它是公式识别的关键环节,该方法对公式结构具有较好的适应性。

Based on introducing briefly the development state of mathematical formula recognition,this paper puts forward a mathematical formula recognition model based on recursion strategy.The model consists of the page layout analysis and mathematical formula structure representation.The page layout analysis is mainly used to extract the mathematical formula from the document,and the representation of mathematical formula structure is made with tree structure adopting recursive algorithm,which is a key link for the formula recognition,and this method has powerful adaptability to the formula structure.
