About this Dataset

NIST Fingerprint Image Quality (NFIQ) 2 Conformance Test Set

The images and values in this dataset are used to ensure conformance with ISO/IEC 29794-4, which may be purchased from https://www.iso.org/standard/62791.html. Values were computed with NIST's NFIQ 2 software, https://github.com/usnistgov/NFIQ2. When compiling the NIST NFIQ 2 source code or developing their own alternate implementation of quality metrics contained within ISO/IEC 29794-4, Annex A of the standard requires that the developer ensure that software generate values within 1% of these values when using these images as input.
