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.
