FINGERPRINT COLLATION APPARATUS, FINGERPRINT COLLATION METHOD, AND FINGERPRINT COLLATION PROGRAM

摘要

The overlapping parts of a plurality of partial images of a fingerprint inputted through a fingerprint input device (7) are corrected and the image is reconstructed by a reconstructing unit (106). The feature is extracted by a fingerprint feature extraction unit (110) and stored in an input feature memory. A collation unit DP-compares the feature stored in the input feature memory with the feature stored in a registered feature memory (a dynamic planning method) and compares the distance value determined with a preset threshold value. The collating unit judges that they agree with each other if the distance value is smaller than the threshold value; but it judges that they don't if the distance value is larger than the threshold value.
