摘要

为了对文档图像中的数学内容进行高层次的理解，对数学区提取和识别技术的需求是显而易见的。本文提出了一种仅利用数学公式和方程的空间布局信息对文档图像中显示的数学区域进行全自动分割的方法，以帮助商用OCR系统识别数学区域，同时也为其他OCR系统对数学符号的识别和排列提供帮助。

Automated segmentation of math-zones from document images

With an aim to high-level understanding of the mathematicalcontents in a document image the requirement ofmath-zone extraction and recognition technique is obvious.In this paper we present fully auotmatic segmentation ofdisplayed-math zones from the document image, using onlythe spatial layout information of math-formulas and equations,so as to help commercial OCR systems which cannotdiscern math-zones and also for the identification and arrangementof math symbols by others.
