摘要
分析了几种指纹自动识别方法的优缺点，提出了一种新的识别方法：有向图集法．此法中，结点表示指纹中隆线上的分叉点，有向边表示这些分叉点之间的关系．此外。
After analysing the advantages and disadvantages of several methods for the recognigtion of fingerprint patterns, this paper put forward a new method for their recognition —the method of directed graph set. In this method the nodes correspond to bifurcations. on the ridges. The directed edges explain the relationship between the bifurcations. And it also presxents two algorithms for directed grqph set matching and fingerprint pattern recognition.
