This new NIST fingerprint database offers the user complete paired fingerprint cards that include all ten rolled fingerprints and the plain/flat impressions at the bottom of the card. Paired fingerprint cards are two sets of fingerprints for one individual captured at different dates. By including all the fingerprint data for the card pairs, a user can compare any combination of plain and rolled images. This database has 216 paired fingerprint cards. Each card is scanned at 19.7 ppmm (500 ppi) and segmented into individual fingerprint images. The segmented images are compressed using WSQ compression at a compression ratio of 15:1 and stored in the ANSI/NIST data format. Reference information is included in comment fields to help reconstruct the fingerprint card image if desired as well as a human defined classification for each fingerprint image.
