An Modified Fingerprint Classification Method

Abstract

Abstract: We propose a new method which uses not only the directional information of ridges, but also the structural information of ridges, in addition, we use the singularities in the fingerprint. classification. This method improves the accuracy. In the method, we classify the fingerprints into S kinds: whorl, right loop, left loop, arch and tent arch. The method has been proved to be efficient.

摘要： 提供一种改进的指纹分类算法,该算法不仅利用了脊的方向信息而且还利用了脊的结构信息和指纹图像中的奇异点,提高了分类的准确度。在此将指纹分为5类:涡型、右旋型,左旋型,弓型,弧型。实验表明这种算法精确度高,结果可靠。
