Overview

The Slap Fingerprint Segmentation Evaluation 2004 will investigate the accuracy of fingerprint image segmentation systems for use with multi-finger slap images.

The segmentation application to be tested is assumed to run on Windows 2000 or Red Hat Linux 7.2, on x86 platforms. Other options must be approved by the Test Liaison. The application must have a command-line interface, as specified in this document: no other user interface is permissible.

The segmentation application must be capable of taking as input either a Wavelet Scalar Quantization (WSQ) compressed slap image, or an uncompressed raw slap image, and outputting up to four uncompressed raw segmented images, each corresponding to one of the individual fingers pictured in the slap.

NIST has public domain WSQ tools in its NIST Fingerprint Image Software (NFIS); see http://www.itl.nist.gov/iaui/894.03/databases/defs/nist_nfis.html. Alternatively, a variety of commercial vendors of WSQ tools can easily be found by doing an Internet search, e.g. for "wsq compression software."
