Abstract  A new fingerprint alignment algorithm is presented in this paper. A multiresolution method for singular point localization in fingerprint images is used, which can not only ensure location precision, but also decrease the probability of error and the computational time. By fingerprint orientation field analysis, the direction of the core is computed accurately and quickly. According to the location and direction of registration point, the live scanned fingerprint can be aligned with the fingerprints in the database. Compared with the common pointpattern alignment algorithm, the complexity of proposed algorithm is lower. Experimental result shows that the alignment using the proposed algorithm can get high precision and efficiency, which is practicable and advantageous to fingerprint matching.
