ADAPTIVE DIC7IONARY FOR A FINGERPRINT RECOGNIZER BACKGROUND OF THE INVENTION The present invention relates, in general, to fingerprint pattern recognition, and more particularly, to a method for fingerprint recognition with learning capability. A fingerprint recognition apparatus is well known which recognizes a fingerprint pattern, stores the pattern in memory, and compares the subsequent entry of a fingerprint pattern with the stored fingerprint pattern to provide a correspondence signal when they correspond with each other. For example, a fingerprint comparison apparatus is disclosed in Japanese Patent Publication No. 76964, 1988 where in a fingerprint image to be checked is compared with a registered fingerprint image, said apparatus including a monitor which displays the fingerprint image of the finger to be compared and an indicator displaying a finger position guide on the monitor screen. Furthermore, in Japanese Patent Publication No.149776, 1988, a fingerprint comparison apparatus is disclosed wherein a fingerprint is scanned several times for one finger at the fingerprint scanning section during fingerprint data registration and one piece of the data captured through several sessions of scanning is registered and stored as reference fingerprint data. In this fingerprint comparison system, other scanned data are compared with the reference fingerprint data to compute the rate of correspondence, which is registered and stored, whereupon the fingerprint scanned at the fingerprint scanning section is compared with said reference fingerprint data to determine the rate of correspondence, by means of which the correspondence of the scanned fingerprints is judged on the basis of whether or not the above rate of correspondence exceeds the reference level determined according to said registered and stored rate of correspondence. In prior art fingerprint recognition apparatus, an optical signal of a fingerprint pattern is resolved into num
