ABSTRACT:
A tenprint selector comprises a fingerprint pattern level feature difference calculating unit which receives and compares a set of candidates for pattern level feature types of fingerprint images shown on file cards and a set of candidates for pattern level feature types of fingerprint images shown on a search card and calculates a pattern level feature difference, a card difference calculating unit which calculates a card difference based on the pattern level feature difference of the fingerprint images of all fingers shown on the file cards and the search card, and a judging unit which compares the card difference determined by the card difference calculating means with a predetermined card difference threshold value and judges, whether the file card shall be selected to be further checked with the search card.
