A Comprehensive Approach for Fingerprint Alignment

Fingerprint alignment is a challenge task due to the pose of fingerprint image acquirement and the deformation and noise of fingerprint image. A comprehensive method to align fingerprints is proposed in this paper. As an intrinsic characteristic, orientation field of fingerprint is robust to the deformation and noise, a novel method calculating orientation difference is used to measure the similarity of fingerprint roughly, by combining orientation difference with ridge and minutiae information, the optimal alignment be obtained through measuring the global comprehensive similarity. The results of experiment conducted on FVC2002 DB3 testify the effectiveness of the proposed approach.
