Description of WSQ image library (for fingerprints)
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 11 other graphic file formats, it is small (~ 1.5 Megabyte) and fast, and has graphics format conversion utility. Supported formats for reading: WSQ - FBI's Wavelet Scalar Quantization BMP - Windows Bitmap Graphics TIFF - Tagged Information File Format PNG - Portable Network Graphics JPEG - Joint Photographic Experts Group RGB - Silicon Graphics International TGA - Truevision Targa Graphic GIF - Compuserve Graphic Interchange Format CEL - Animator Graphic (FLC and FLI formats) PSD - Adobe Photoshop (LAB or CMYK formats not supported) IFF - Amiga Bitmap Graphic (8 bits) PCX - PC Paintbrush Bitmap Graphic 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.
