| 摘 要： | 手写体汉字字符切分是离线汉字字符识别预处理中的一个重要问题，针对离线手写体汉字，提出一种基于笔划提取和合并的手写体汉字字符切分算法。该算法首先基于方向游程提取汉字的笔划，并建立笔划框，再根据汉字笔划的结构知识对笔划框进行合并，得到字符的切分结果。该算法能较好地解决粘连汉字字符的切分问题，对从现场随机采集的2500封手写体信函地址汉字进行切分，单字正确率可达91．5％。

| Abstract: | Segmentation of handwritten Chinese characters is an important task for preprocessing of Chinese character recognition. A new algorithm for handwritten Chinese character segmentation based on extracting and knowledge\|based merging of stroke bounding boxes is proposed in this paper. The knowledge\|based merging operations are used to merge stroke bounding boxes according to the structure feature of Chinese characters. The experiment shows the new algorithm is very effective for off\|line handwritten Chinese character segmentation. |
