改进的Gabor滤波算法在指纹识别中的应用

Improvement of Gabor filtering algorithm and its application minutiae extraction of fingerprint

指纹自动识别系统中图像的处理和匹配算法在系统的设计中起了尤为重要的作用,本文对Gabor滤波算法进行了简化,同时引入了HGF(Half Gabor Filter)对指纹图像进行了增强处理。实验结果表明经过这种改进的Gabor滤波算法提高了图像的处理速度,并很好的保留纹线的关键信息。

The Fingerprint image enhancement and matching Algorithm is very importment in the automatic fingerprint identification system.the original extended Gabor filtering algorithm is simplifier and using the Half Gabor fiter enhance the fingerprint image.
