| 摘 要： | 在印刷体数学公式识别中，不能很好地切分粘连字符是造成识别错误的主要原因。针对这种情况，提出了一种基于滑动窗口切分粘连字符的方法。通过特征值比较．提取出粘连字符，然后对粘连字符切分。实验表明，这种方法使识别率得到了提高。

| Abstract: | Touching characters cannot be segmented which is the main reason for false recognition of typeset mathematical expressions. To solve this problem, a technique which is based on sliding window technique is presented for the segmentation of touching characters in mathematical expressions. Through comparing the feature value , the touching characters are detected .Then the touching characters are segmented. Experimental results show the effectiveness on the accuracy improvement of mathematical expression recognition. |

| Keywords: | mathematical expression recognition symbol recognition touching character residual image |
