The NIST database of mated fingerprint card pairs consists of multiple volumes. Currently five volumes have been released.
Each volume will be a 3-disk 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 non-standard implementation of the JPEG lossless compression algorithm.
Each CD-ROM requires approximately 630-660 megabytes of storage 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 SUN 4/470 SPARCserver. The software is the same code used with NIST Special Database 4.
NIST Special Database 9 has the following features:
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.
