C. Quentin Davis and Dennis M. Freeman Presented at the ARO midwinter meeting, February 1995.
You can read the abstract or the talk. The talk's movies won't be as nice here as they were at the conference, because the mpeg player (at least mine) is slow, and has funny startup/ending transients. Also, if you can convince your mpeg player use grayscale dithering (on pseudocolor displays), the images will look much better.
