I'm looking for an image processing suite. You know, the standard type of functions: gradient edge detection, histogram equalization, FFT, binary ops (XOR, OR, AND). I'll even accept a reference to a "cheap" off-the-shelf library, but its gotta' be written in C. Thanks. -- Richard M.

I could send you the docs (about 38K) if you want, perhaps you could get the source from above. Billy Harvey wxh@a.lanl.gov

It is a significant collection of image processing algorithms from the NYU Psychology Dept. The algorithms are organized as Unix filters, together with a library to manipulate a standard image header. The distribution also includes a SunView based image previewer. HIPS is not public domain, but relatively inexpensive for "public institutions". It is distributed as C source code.

Box 373, Prince Street Station New York, NY 10012-0007 ---------------------------------- Below is a summary of the kind of things that were found in the HIPS package a few years ago, I believe it has expanded somewhat since then. (This message implies no endorsement of the HIPS product - it is simply meant to reflect the fact that HIPS has been useful to us, and MIGHT be useful to you.)
