The WSQ file extension is used to refer to Wavelet Scalar Quantization files that are used in the Wavelet program’s compression technique. Wavelet WSQ files are compression algorithm files and are used to compress and reduce the size of bitmap images. WSQ files can be accessed and edited with the appropriate software.
The Wavelet Scalar Quantization algorithm (WSQ) is a compression algorithm used for gray-scale fingerprint images. It is based on wavelet theory and has become a standard for the exchange and storage of fingerprint images. WSQ was developed by the FBI, the Los Alamos National Laboratory, and the National Institute of Standards and Technology (NIST).
