What is a .WSQ file extension?

.WSQ file extension has been classified as Bitmap image Files.

.WSQ is Wavelet-packet Scalar Quantization bitmap

The wsq file extension is related to Wavelet-packet scalar quantization bitmap file format.

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).

This compression method is preferred over standard compression algorithms like JPEG because at the same compression ratios WSQ doesn't present the "blocking artifacts" and loss of fine-scale features that are not acceptable for identification in financial environments and criminal justice.

.WSQ file format is deprecated and this file format is no longer supported.

Currently, .WSQ file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.
