摘要
在自动指纹识别系统中,指纹细化占有重要地位。本文讨论一种新的细化算法,将方向图引入指纹图像的细化,结合形态学细化算法,改进了传统细化算法不尽如人意的方面,取得了良好的细化效果。
Thin of fingerprint image is a very important process in automatic fingerprint indentification system AFIS. This thesis proposes a new algorithm of thin by using direction map. Combining with morpholopy thin algorithm it overcomes disadvantage of trandition method and works more effectively.
