摘要

The present invention relates to a system and method for the comparison of fingerprints independent of the type of minutia descriptor. The system is effective in the verification of fingerprints and fingerprints, as well as in the identification of fingerprints and fingerprints. The method performs multiple alignments of the tracks and for each alignment finds a cluster of matches. The clusters are mixed from higher to lower weight to cover the entire footprint independently of their global deformations. Then a thin-plate spline model is constructed from the mixed clusters and with this new matching minutiae are found. The resulting similarity value is calculated from the weight of all matching minutiae found. (Machine-translation by Google Translate, not legally binding)
