Free NIST (ANSI/NIST-ITL 1-2000) viewer. Version 1.0. Cognaxon NIST (ANSI/NIST-ITL 1-2000) viewer reads and extracts NIST (ANSI/NIST-ITL 1-2000) file format. The advantage of NIST files is the ability to contain multiple images and other types of data about the person in one single file, which simplifies biometric data exchange between participating parties. As for example: one WSQ file contains only one fingerprint image, but one NIST file contains inside many fingerprint images and also other information. ANSI/NIST-ITL 1-2000 is Data Format for the Interchange of Fingerprint, Facial, & Scar Mark & Tattoo (SMT) Information defined by American National Standard for Information Systems. One single NIST (ANSI/NIST-ITL 1-2000) file is able to contain following types of data: Type-1 Transaction Information Type-2 Descriptive Text (User-defined) Type-3 Fingerprint Image Data (Low-resolution grayscale) Type-4 Fingerprint Image Data (High-resolution grayscale) Type-5 Fingerprint Image Data (Low-resolution) Type-6 Fingerprint Image Data (High-resolution) Type-7 Image Data (User-defined) Type-8 Signature Image Data Type-9 Minutiae Data Type-10 Facial & SMT Image Data Type-11 Reserved for Future Use Type-12 Reserved for Future Use Type-13 Latent Image Data (Variable-resolution) Type-14 Tenprint fingerprint Impressions (Variable-resolution) Type-15 Palmprint Image Data (Variable-resolution) Type-16 User-defined Testing Image Data (Variable-resolution) NIST (ANSI/NIST-ITL 1-2000) viewer is the demo version of NIST (ANSI/NIST-ITL 1-2000) library add-on available as SDK for software developers.

For fingerprint images WSQ (Wavelet Scalar Quantization) is superior to other lossy compression methods, such as JPEG, and was chosen by FBI (U.S. Federal Bureau of Investigation) as the fingerprint image compression standard. WSQ is a lossy compression method that is well-suited for preserving the very high resolution details of grayscale images while maintaining high compression ratios of typically 12:1 to 15:1. Cognaxon WSQ image library provides the easy way to add WSQ image format support to your software projects. WSQ image library reads and converts between WSQ and 31 other graphic file formats, it is small (~ 1.5 Megabyte) and fast, and has graphics format conversion utility. Supported formats for reading: WSQ, BMP, TIFF, TIF, JPG, JPEG, JPE, PNG, GIF, PSP, JFIF, RLE, DIB, TGA,WIN,VST,VDA,ICB, FAX, EPS, PCX, PCC, SCR, RPF, RLA, SGI, RGBA, RGB, BW, PSD, PDD, PPM, PGM, PBM, CEL, PIC, PCD, CUT, IFF, ICO, WMF, EMF. Supported formats for writing: WSQ - FBI's Wavelet Scalar Quantization, BMP - Windows Bitmap Graphics, TIFF - Tagged Information File Format (no LZW compression), PNG - Portable Network Graphics, JPEG - Joint Photographic Experts Group, RGB - Silicon Graphics International (uncompressed), TGA - Truevision Targa Graphic. Adding WSQ image library to your software project is very easy. Only 2-3 steps and several lines of code are needed. Sample projects are provided for: Microsoft Visual C++ / Microsoft Visual C++ .NET, Microsoft Visual C# .NET, Microsoft Visual Basic, Microsoft Visual Basic .NET, Borland C++ Builder, Borland Delphi, Sun Java, NetBeans Sun Java, Eclipse Sun Java, MinGW C/C++, Eclipse C/C++, Code::Blocks C++, Bloodshed Dev-C++, Borland C++ for Win32, Digital Mars C/C++, MatLab, Compaq Visual Fortran, PowerBASIC, MASM32 (32 bit Microsoft Assembler).
