Abstract

Fingerprints are usually compared based on the matching of such features as ridge bifurcations and endings. However, when features are extracted from a thinned fingerprint, pseudo-features are usually introduced as well. In this paper, we propose an approach in which points on a fingerprint ridge can be traced and recorded in a chained list with a 3 X 3 window. based on the proposed approach, an algorithm to remove pseudo-features from a thinned fingerprint image is developed. The algorithm is carried into execution using a library of thinned fingerprint images with such pseudo-structures as spurs, bridges and circles, and it is found that the pseudo-features can be correctly and totally removed with high efficiency.
