-
摘要: 汉字是二维平面上的线划图形,在线汉字识别的一个有利条件是利用书写时的笔段顺序 信息,从而采用一维的表示.然而不同的人书写同一个字时笔顺会有所不同,这就给汉字的处 理与识别带来困难.本文给出一种以笔段为基础,仅依赖汉字字形结构的排序方法,把二维空 间的笔段在一维空间排出稳定的次序.这一次序与笔划的书写序无关.这就为在线手写汉字 的识别打下了良好的基础.Abstract: A Chinese character is a 2-D line-drawn pattern. In order to get a 1 D representation, the order of strokes is often applied to online Chinese character recognition. But the order of strokes may be different for different writers. A method of linesegment ordering is proposed in this paper. It can provide stable order independent of the writing order of characters. On the basis of this method, high performance online handwritten Chinese recognition can be obtained.
