WSQ image library (for fingerprints) v.2.8

reads and converts wsq (fbi's wavelet scalar quantization) and 31 other formats. for fingerprint images wsq (wavelet scalar quantization) is superior to other lossy such as jpeg, and was chosen by fbi (u.s. federal bureau of investigation) as the fingerprint image compression standard.
