Abstract

This database is a valuable tool for evaluating fingerprint systems on a statistical sample of fingerprints which is evenly distributed over the five major classifications.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.
