【Abstract】 In the aspect of feature extraction and post-processing,an effective approach to eliminate false features is presented.The elimination algorithm of false features is based on structural information of all kinds of noises in thinned fingerprint images and the distributing disciplinarian of fingerprint features.It is found that the approach is simple and the speed is high.Moreover,the accuracy of minutiae elimination can fill the demand of application.更多还原
