指纹图像识别技术新思路与实验研究
New Idea and Experimental Study of Fingerprint Identification Technology
摘要
Abstract
Fingerprint identification technology is widely used in areas such as identification.The key of preprocess of fingerprint is fingerprint image enhancement.This paper proposes a dynamic fingerprint image enhancement algorithm based on double filter.It has strong ablity to separate the adhesion ridge line by the dynamic 2 demission Gabor filter and to connect fracture ridges with directional filter.The advantages of these two filters are output which is binary image.Gabor filter and directional filter can be used to enhance the image for a second time to achieve better effect.Plenty of experiments show that this algorithm has lower reaction of translation and rotation of fingerprint images.It is advantageous to extract details and easy to implement.关键词
