NIST Special Database 4

NIST 8-Bit Gray Scale Images
of Fingerprint Image Groups (FIGS)

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 prints4.txt and prints4.tar.Z [10,528K].

The NIST database of fingerprint images contains 2000 8-bit gray scale fingerprint image pairs. Each image is 512-by-512 pixels with 32 rows of white space at the bottom and classified using one of the five following classes:
A=Arch, L=Left Loop, R=Right Loop, T=Tented Arch, W=Whorl.
The database is evenly distributed over each of the five classifications with 400 fingerprint pairs from each class.
The images are compressed using a non-standard implementation of the JPEG lossless compression algorithm and require approximately 636 megabytes of storage compressed and 1.1 gigabytes uncompressed (1.6:1 compression ratio).
The database also includes format documentation and example software.
NIST Special Database 4 has the following features:

2000 8-bit gray scale fingerprint image pairs including classifications
400 fingerprint pairs from each of the five classifications - Arch, Left and Right Loops, Tented Arch, Whirl)
each of the fingerprint pairs are two completely different rollings of the same fingerprint
19.7 pixels per millimeter resolution
image format documentation and example software.

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 on a statistical sample of fingerprints which is evenly distributed over the five major classifications.

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