Windows 3.1 implementation of the wavelet fingerprint compression.

This is to announce a free Windows 3.1 implementation of the wavelet-based
FBI standard fingerprint compression algorithm. It can be obtained by
anonymous ftp from:,
in the directory:
as the file:

This is an archive containing the program and a file which is
partially reproduced below. Use PKUNZIP to unpack the archive once you
download it.


TI: WSQ -- the FBI/Yale/Los Alamos [W]avelet-packet [S]calar [Q]uantization
fingerprint compression algorithm, for Windows 3.1 or higher.
AU: He Ouyang and M. Victor Wickerhauser
IN: Washington University in St. Louis
SO: Executable is available by anonymous ftp only
ST: Public software

AB: This is an implementation of the WSQ algorithm as described in ``IAFIS
Use of the Wavelet Scalar Quantization (WSQ) Compression/Decompression
Algorithm," J. J. Werner, 8 December 1992. The implementation is designed
for well-equipped IBM-type desktop computers using the Windows 3.1 operating
system. It reads .BMP files and writes standard-format compressed files, and
vice versa. Results are displayable on a high-resolution video monitor. The
quality factor can be set under menu control. Computations are performed in
integer arithmetic -- no floating-point coprocessor is needed.
