摘要

滤波技术是指纹预处理中的关键步骤.本文提出了一种基于脊向指纹滤波预处理方法.首先利用改进后的极值滤波器对指纹图像进行滤波

再用本文所提出的脊向滤波器对结果进行处理.实验结果验证了此方法的有效性.

Abstract

The filtering method is the key procedure in the preprocessing for fingerprints image.In the paper

a new algorithm of fingerprint images based on the filtering of the ridge direction is introduced.First

an improvement of extreme value filtering is presented and then

an algorithm of fingerprint images based on the filtering of the ridge direction is discussed.Our experiments show that method is satisfactory.
