announces a new database
NIST Special Database 9
8-Bit Gray Scale Images of Mated Fingerprint Card Pairs (MFCP)
The NIST database of mated fingerprint card pairs will consist of multiple
volumes. Currently five volumes are scheduled to be released. Volumes 1-3
have been released and volumes 4 and 5 will be released by the middle of
June. Each volume will be a 3 CD-ROM set with each CD-ROM containing 90
mated card pairs of segmented 8-bit gray scale fingerprint images (900
fingerprint image pairs per CD-ROM). Each segmented image is 832 by 768
pixels and classified using the National Crime Information Center (NCIC)
classes given by the FBI. The images are compressed using a modified JPEG
lossless compression algorithm. Each CD-ROM contains approximately
630-660 Megabytes of data compressed and 1.0-1.2 Gigabytes uncompressed
(1.8 : 1 average compression ratio). The database also includes example
software which was written on a UNIX environment workstation. The software
is the same code used with NIST Special Database 4.
NIST Special Database 9 has the following features:
o Each Volume has 270 mated card pairs of segmented 8-bit gray scale
fingerprint images.
o NCIC classifications given by the FBI.
o Cards selected randomly thus approximating a natural horizontal
slice of the NCIC classifications.
o Resolution of approximately 11.0 line pairs per millimeter resolution. Scanned at 19.6850 pixels per mm.
o Image format documentation and example software (written on a
UNIX environment workstation)
o Software is the same code used with NIST Special Database 4.
Suitable for automated fingerprint classification research, the database can
be used for:
o algorithm development
o system training and testing
The database is a valuable tool for evaluating fingerprint systems using a
statistical sample of fingerprints which approximate a natural horizontal
slice of the NCIC classifications. The system requirements are a CD-ROM drive
with software to read ISO-9660 format and the ability to compile the C source
code, which was written using a SUN C compiler. Cost per volume of the
database: $750.00.
