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.

format support to your software projects. WSQ image library reads and
