接触符号不能准确切分是造成排版数学公式误识别的主要原因之一。针对这一问题，提出了一种基于轮廓特征的数学表达式中接触符号的分割方法。首先根据轮廓特征和宽高比建立分割路径，然后对接触符号进行分割。实验结果表明，该方法对提高数学公式识别的准确率是有效的。
Touching symbols cannot be segmented accurately which is one of the main reasons for false recognition of typeset mathematical expressions. To solve this problem, a technique which is based on contour feature is presented for the segmentation of touching symbols in mathematical expressions. Partitioning paths can be constructed ground on contour feature and the ratio of the width and the height, and then touching symbols are segmented. Experimental results show the effectiveness on the accuracy improvement of mathematical expression recognition.
