I am trying to find a ready made program that I can incorporate into
an image processing system here at PSU.  I've seen many programs in
Fortran, unfortunately, they are hard to understand and hard to port
to C.  Specifically, I've been looking at "Programs for Digital Signal
Processing" published by IEEE ASSP in 1979.  One of the obstacles I've
come across is the fact that the 2-D matrix I need to use this on is
not square, it is 256 x 240 pixels, which calls for a multi-variate
program.  An advantage is that I am at least working on real values
rather than complex.

There are supposedly many programs that do this out there.  I would like
to use one rather than re-invent the wheel.  If someone would be so kind
as to either send me source code (commented please!) or where to find it
I would be much obliged.

Thank you, David Gray
