资源简介：
NIST, working with the FBI, has digitized 888 inked fingerprint arrest cards that
were in various physical conditions, from pristine to badly damaged and faded, and were
collected during law enforcement professionals' duties. This database contains images of the
10 rolled fingerprint impressions, the two four-finger slap impressions (finger positions 13
and 14), the two thumb slap impressions (finger positions 11 and 12) and the segmented
impressions from the slap images (13,14). The database also includes the coordinates that were
used to segment the impressions from the slap fingerprint images.\n\nThe cards were scanned at
three different resolutions: 500, 1,000, and 2,000 pixels per inch (PPI). All three
resolutions were scanned in grayscale at a depth of 8 bits-per pixel.\n\nData available as of
July 2018 is Special Database 300a, in 500 ppi with PNG formatted impressions. Data at other
resolutions, in other image formats, and in other record types may be
forthcoming.
