摘要 字符切分是字符识别系统的一个重要环节。粘连则是指字符图像间有笔画接触的情况,它普遍存在于手写和低质量的印刷文档中。然而普通切分算法很难处理粘连字符。本文综述了主要的粘连字符切分算法以及切分路径的评价方法,在详细介绍算法流程的基础上,对每种算法的优缺点以及粘连字符切分的未来工作进行了探讨。 Character segmentation is a key step of a character recognition system. In this step it is most difficult to separate connected characters or touching characters, which occur frequently in handwritten documents and printed ones with low quality. This paper focuses on segmentation of touching characters. It surveys 5 approaches that construct segmentation paths or candidates and 3 evaluation functions that are used to select the best path. Based on the discussion of the advantage and disadvantage of each approach,some promising directions are proposed.
