Lines: 34 Okay to discussion image processing type questions (analysis as opposed to synthesis): here is a good posting. The fellow has asked me to post for him because his news software has problems Please make to him directly, not me. --eugene ============================ ========================= From: Richard Outerbridge Hi, I'm a grad student in Oceanography at Dalhouise in Canada. > Editing of a personal message at this point asking reposting thanks in advance, Richard the following bit is what i tried to send out. ---------------------------------------------------- I have two planar fields from which I intend to construct two false colour images. In doing this in the past I have noticed that the two images are similar. I would like to have some method of quantifying this similarity, perhaps even a method for determining how one image (or original field) derives from the other (i.e. by what combination of rotation, transposition, re-scaling, etc. one can best approximate the transformation). Any help you can provide would be greatly appreciated. P.S. Please reply be e-mail directly to me if possible. Our connection to the NEWS net is experimental and subject to the whims of the folks in leisure suits. From: Richard Outerbridge
