摘　　要：引入方向代码的概念,将联机手写笔画的运动轨迹转换成由方向代码组成的序列。通过分析代码序列中的噪声因素,归纳了噪声的种类,进而设计并实现了一种基于方向代码序列的滤波算法,为联机手写汉字的识别奠定了基础。结合实验完成了滤波、归并和匹配各个过程的设计,从而完成了单笔画及连笔部件的识别。Introducing the concept of direction code, the moving track of online handwritten stoke is converted to a sequence of direction code. Through analyzing the noise factors in the code sequence, the noise kinds are generalized, and then a filtering algorithm based on direction code sequence is designed and implemented, which lays a foundation for online handwritten Chinese character recognition. The design of filtering, merging and matching is completed by combining experiments, thus the recognition of singre stroke and cursive components is achieved.
