I prefer the quote made by Dr. Azriel Rosenfeld a few years ago on the topic of computer graphics/processing/imaging: The world can be broken into four pieces; the first has nothing to do with images. The second is generally called computer graphics and deals with generating visible images from numbers (display a line drawn from 0,0 to 1,1). The third, image processing, deals with generating an image from another image, generally with certain enhancements. The fourth, computer vision, deals with generating numbers from images (reading the numbers from bank checks). So, we get: 1. numbers -> computer -> image (show me the line) 2. image -> computer -> image (anti-alias this image) 3. image -> computer -> numbers (what was that check number?) For the net.graphics group, I think enough overlap in various areas exist that a good number of the people will be subscribing to all sub-groups. -tcs Terry Slattery U.S. Naval Academy 301-267-4413 ARPA: tcs@brl-bmd UUCP: decvax!brl-bmd!usna!tcs
