Sounds like an interesting discussion topic. I'll try a shot at it. I think of IMAGE PROCESSING as that area of GRAPHICS that concerns itself with projections (usually 2D) of the REAL WORLD. (A lot of graphics work is concerned with SYNTHETIC pictures.) The sorts of processing that we're used to considering "image processing" is enhancehent and/or recognition of what the original real-world object was. This group tends to deal with COMPUTER GRAPHICS and COMPUTER IMAGE PROCESSING, but (as Nitin rightly points out) eyeglasses do image processing of the "enhancement" type, and I know some advertising types who are "graphics" experts and don't know thing one about computers. (This is NOT a proposal to broaden submissions to this group; MY interests are computer graphics. Just pointing out that our use of the language is a little parochial.) As for net.graphics.image, I agree that we ought to wait until there are enough postings that there are complaints of clutter.

I use synthetic to also cover enhanced/processed/munched-on/any-way-transformed version of a digitized "real" image. However one there is one fundemental difference which I like to use when the distinction between CG and IP must be made (mostly for "political" reasons). I tend to talk about IP when the BOTH the source and the destination of an operation is an image, and CG whenever the source is a high-level description, such as a geometric model, a descrition of a function in algorithmic form, an artis's nightmare and so on. Of course, there are gray areas espeicially in artistic application, where both real images and "abstract thingamajigs" are used together to produce the desired effect (But mayge that discussion could warrant the creation of net.graphics.art ?) Then you maight say, "What about applictaions of IP where the final result is not necessarily an image but, as Dave writes :" > ...

Some people divide this sort of thing from IP with yet another buzz-term: COMPUTER VISION (CV). These can be recognition programs, printed circuit board fault checkers, road followers, ... A very good, although not the most recent collection of technical papers describing some "PhD winning" vision systems can be found in the Artificial Intelligence Journal, Vol. 17 (special vision issue). -- Gyorgy Fekete --- University of MD, Computer Vision Lab, (301) 454-4526 gyuri@cvl.{ARPA,CSNet} ...seismo \ ...allegra +-- !umcp-cs!cvl!gyuri.UUCP ...brl-bmd /
