The National
Institute of Standards and Technology in conjunction with the Federal
Bureau of Investigation has developed a new database of grayscale fingerprint
images and corresponding minutiae data. NIST Special Database 27
contains latent fingerprints from crime scenes and their matching rolled
fingerprint mates. This database can be used to develop and test new
fingerprint algorithms, test commercial and research AFIS systems, train
latent examiners, and promote the ANSI/NIST file format standard.
In all there are
258 latent cases. Each case includes the latent image, the matching
tenprint image, and four sets of minutiae that have been validated by
a professional team of latent examiners. One set of minutiae contains
all minutiae points on the latent fingerprint; the second set contains
all minutiae points on the tenprint mate; the other two sets contain
the minutiae points in common between the latent fingerprint and tenprint
mate. In all there are 27,426 minutiae recorded across the set of tenprints
with 5460 minutiae in common with their matching latent fingerprint.
Each image is (800x768) pixels in size and has been scanned at 19.69
pixels per millimeter (ppmm) (500 pixels per inch (ppi)), quantized
to 256 levels of gray, and stored in an uncompressed format. All data
files are formatted according to the ANSI/NIST-ITL 1-2000
standard using Type-1, 9, 13, & 14 records. Software utilities are provided
to read, write, and manipulate these files.
This database
is distributed on an ISO-9660 CD-ROMs utilizing 317 megabytes of
storage.
Examples from
this database are available at: sd27.tar
Source code for
reading, writing, and manipulating ANSI/NIST data files is available
