NIST Biometric Images Software

Biometric image software distribution developed by the National Institute of Standards and Technology (NIST) for the Federal Bureau of Investigation (FBI) and Department of Homeland Security (DHS). Provided is a collection of application programs, utilities, and source code libraries. The NBIS software is organized in two categories: non-export controlled and export controlled. The non-export controlled NBIS software is organized
into five major packages: 1. PCASYS is a neural network based fingerprint pattern classification system; 2. MINDTCT is a fingerprint minutiae detector; 3. NFIQ is a neural network based fingerprint image quality algorithm, 4. AN2K7 is a reference implementation of the ANSI/NIST-ITL 1-2000 “Data Format for the Interchange of Fingerprint, Facial, Scar Mark & Tattoo (SMT) Information” standard; and 5. IMGTOOLS is a collection of image utilities, including encoders and decoders for Baseline and Lossless JPEG and the FBI’s WSQ specification. The export controlled NBIS software is organized into two major packages: 1. NFSEG is a fingerprint segmentation system useful for segmenting four-finger plain impressions, 2. BOZORTH3 is a
minutiae based fingerprint matching system. The NFSEG and BOZORHT3 software are subject to U.S. export control laws It is our understanding that NFSEG and BOZORTH3 software fall within ECCN 3D980, which covers software associated with the development, production or use of certain equipment controlled in accordance with U.S concerns about crime control practices in specific countries. This source code is written in ANSI “C”, and has been developed to compile and execute under the Linux operating system and MAC OS-X operating system using the GNU gcc compiler and gmake utility. The source code may also be installed to run on Win32 platforms that have the Cygwin library and associated tools installed. A Reference Manual describing each program in the distribution is included at the end of this document.
