摘　　要：本文将点阵图的边缘定义为有向边界,并据此提出了分两步来实现点阵图矢量化的新方法——有向边界法。该法与其他方法相比,具有算法简单、运行时间短、效率高等优点。The outlines of dot matrix image have been, defined as directed boundaries. Based on this, a directed boundarjr method which veciorizes the dot matrix images with two steps, has been put forward in this paper. Compared with other methods, this method has the advantages of simple algorithm, short run timo and high efficiency, etc.
