A fingerprint recognizer using fuzzy evolutionary programming

A fingerprint recognition system is built with two principal components: the fingerprint administrator and the fingerprint recognizer. Fingerprints are identified by their special features, such as ridge endings, ridge bifurcation, short ridges and ridge enclosures, which are collectively called the minutiae. The fingerprint administrator uses the method of gray-scale ridge tracing backed up by a validating procedure to extract the minutiae of fingerprints. The fingerprint recognizer employs the technique of fuzzy evolutionary programming to match the minutiae of an input fingerprint with those from a database. Experimental results show the methods used are highly effective.
