Abstract
The invention relates to an automatic fingerprint identification method. In the method according to the invention, identification is executed in three phases. In coarse alignment (), fingerprints are compared using a few reference points. In fine alignment (), coincidence of fingerprint minutiae are used to find the best fingerprint matching transformation. In the matching phase (), individual minutiae of the fingerprint examined are matched against a known template. Parameters are computed from the matching minutiae and used in making the final identification.
