#15 Question: Wavelets in forensics

Many police agencies have discovered that FFT filters can benefit them
in removing patterns from images that contain fingerprint patterns
over a repeating pattern (a bloody fingerprint on a piece of cloth,
for example). This is most commonly applied by utilizing the FFT in
Media Cybernetics' Image-Pro Plus or through one of the available
Photoshop plug-in FFT's.

I am interested in a couple of things - first, if anyone knows of
better wavelets that can be used specifically for the purpose of
removing patterned backgrounds, and retaining a fingerprint pattern. I
am specifically looking for something that is easy to use, and that
isolates the fingerprint pattern.

Second, I am looking for programmers who can help with an image
editing/image enhancement application specifically for use in law
enforcement. I already know of the interface I intend to use, the
needed tools, filters, etc. but I am NOT a programmer. This would be a
joint effort, intended to run on Windows 95. It would have some of the
features of an image editing application (like Photoshop) and also
some image analysis program features (convolution filters, for
instance). However, it would also eliminate many of the tools in each
type of program that are useless in law enforcement applications.

If anyone can help with either of these requests, please contact me.
