BIOMETRIC IDENTIFICATION BY FINGERPRINT IDENTIFICATION

摘要

The invention concerns a biometric method for fingerprint identification, by comparing an image of the fingerprint to be identified with an image of a reference fingerprint. The invention is characterized in that it comprises prior steps of determining (E4) an invariant center from lines reproducing the fingerprint structure, on the fingerprint image to be identified, centering (E7) the fingerprint to be identified, based on the previously determined invariant center.
