In August 2004 NIST published a novel measure of fingerprint image quality, which can be used to estimate fingerprint match performance. The definition and methodology of NIST Fingerprint Image Quality (NFIQ) is documented in  and its implementation is publicly available; but subject to US export control laws; as part of NIST Fingerprint Image Software 2 (NFIS2) distribution . This document provides a conformance test of an installation of NFIQ from NFIS2 to NFIQ that was developed, tested and published by NIST in August 2004.
