NIST Special Database 14

NIST Mated Fingerprint Card Pairs 2 (MFCP2)

Price: $90.00

A sample of the data contained in this database is available via anonymous ftp at sequoyah.ncsl.nist.gov in the files prints14.txt and prints14.tar.Z [14,462K].

NIST Special Database 14 is being distributed for use in development and testing of automated fingerprint classification and matching systems on a set of images which approximate a natural horizontal distribution of the National Crime Information Center (NCIC) fingerprint classes and were compressed using an implementation of the wavelet scalar quantization (WSQ) compression specification.

The database consists of three CD-ROM disks, each containing 9,000 image pairs and requiring approximately 670 megabytes of storage compressed and 11.5 gigabytes uncompressed (18.0:1 average compression ratio).

Each segmented image is 832 by 768 pixels and classified using the NCIC classes given by the FBI. The database also includes example software which was written on a SUN SPARCserver.

NIST Special Database 14 has the following features:

• 27,000 pairs of segmented 8-bit gray scale fingerprint images
• Images compressed with an implementation of the WSQ compression specification
• NCIC classifications given by the FBI
• Cards selected randomly thus approximating the natural horizontal distribution of the NCIC classifications.
• Scanned at 19.7 pixels per mm.
• Image format documentation and example software (written on a SUN SPARCserver)
• The first 13,500 fingerprint images are the same as the images losslessly archived in NIST Special Database 9, Volumes 1-5.

Suitable for automated fingerprint classification research, the database can be used for:

• algorithm development
• 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 distribution of the NCIC classifications and were compressed with an implementation of the WSQ compression specification.

System Requirements: CD-ROM drive with software to read ISO-9660 format and the ability to compile SUN C source code.
