` About
`
`NIST Fingerprint Image Quality (NFIQ) 2 is open source software that links image
`quality of optical and ink 500 PPI fingerprints to operational recognition

`
`performance. This allows quality values to be tightly defined and then numerically
`calibrated, which in turn allows for the standardization needed to support a
`worldwide deployment of fingerprint sensors with universally interpretable image
`qualities. NFIQ 2 quality features are formally standardized as part of ISO/IEC
`29794-4 (http://www.iso.org/iso/catalogue_detail.htm?csnumber=62791) and serve as the
`reference implementation of the standard.
`
`Source code
`
`Development of NFIQ 2 occurs on the official NFIQ 2 GitHub
`(https://github.com/usnistgov/NFIQ2).
`
`Downloads
`
`Installers for major releases are available on the Releases tab of the official NFIQ 2
`GitHub (https://github.com/usnistgov/NFIQ2/releases). These downloads include a
`command-line interface for a variety of platforms, as well as development files for
`third-party integrators.
