A large collection of general-purpose image utilities (IMGTOOLS) are also included to support the processing of fingerprint images. The FBI's Universal Latent Workstation uses MINDTCT, and it too is the only known no cost system of its kind. This system includes minutiae quality assessment based on local image conditions. A minutiae detector called, MINDTCT, automatically locates and records ridge ending and bifurcations in a fingerprint image.It is the only known no cost system of its kind. This is an updated system that includes the use of a robust Multi-Layered Perceptron (MLP) neural network. A neural-network based fingerprint pattern classification system called, PCASYS, automatically categorizes a fingerprint image into the class of arch, left or right loop, scar, tented arch, or whorl.The ability to retrain the NFIQ weights is provided with the utilities FING2PAT, ZNORMDAT, and ZNORMPAT. Higher quality images produce significantly better performance with matching algorithms. fingerprint image quality algorithm, NFIQ, which analyses a fingerprint image and assigns a quality value of 1 (highest quality) 5(lowest quality) to the image. Development of a new major revision of the NFIQ algorithm started in 2011 – further details on NFIQ 2.0 can be found here.The utilities support updated and new record types introduced by this latest version of the standard (Record Types 9, 13, 14, & 15). This reference implementation contains a suite of utilities designed to read, write, edit, and manipulate files formatted according to this interchange standard. A reference implementation of the ANSI/NIST-ITL 1-2007 (AN2K) "Data Format for the Interchange of Fingerprint, Facial, Scar Mark & Tattoo (SMT) Information" standard is included.The NBIS utilities fall under eight general categories: In addition, the NBIS.Net project provides a Microsoft.NET adapter for NBIS, providing an interface to the original NBIS source. The NBIS source code is available to download from NIST Biometric Open Source Server. The NBIS distribution contains C source code for use with biometrics processing and analysis. It has been determined that the export control restriction did not apply to the NFSEG and BOZORTH3 software, due to both being outside the scope of EAR(see Part 734.3 of the EAR for exact details) they are freely distributed and considered public domain. Therefore, it is permissible to distribute this software as a free download from the internet. Government it is freely distributed with no licensing requirements and it is considered public domain. This software has been determined to be outside the scope of the EAR (see Part 734.3 of the EAR for exact details) as it has been created solely by employees of the U.S. The NIST Biometric Image Software (NBIS) distribution is developed by the National Institute of Standards and Technology (NIST) for the Federal Bureau of Investigation (FBI) and Department of Homeland Security (DHS).
