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.
