Research Status of Mathematical Formula Recognition
张 矩 ：中国科学院重庆绿色智能技术研究院，重庆
In order to search and edit the documents which contain mathematical formulas, we must auto-matically recognize the expression. Mathematical formula recognition is an active research field and many approaches have been proposed over the years. Nowadays, there are several forms of input data format such as document images, strokes, vector images and so on. Different ways of inputs determine the methods to extract mathematical formulas and different ways of mathematical formula recognition. This article describes the currently researching work of mathematical formula recognition, discusses the four components problems in mathematical formula recognition: the detection of expression, symbol recognition, structural analysis, interpretation and so on, and points out the future research directions of mathematical expressions.
