Hough transformation implemented as an imageJ plugin-- looks pretty good for finding circles. Also interesting are snakes, fft's, and many more plugins for image i/o and processing... fascinating...

Scanning the fragments of the Forma Urbis Romae
"The single most important document on ancient Roman topography is a map created in ancient times - the Forma Urbis Romae. Measuring 60 feet across, 45 feet high, and carved onto marble slabs several inches thick, it once graced the back wall of the census bureau of Rome (shown here by a yellow arrow), in the Templum Pacis. Carved between A.D. 203 and 211, during the reign of Septimius Severus, it shows every street, building, room, and staircase on the ground floor of the city - a feat of mapmaking that has never been matched. Incidentally, Il Plastico is at the same scale as the Forma Urbis, 240:1."

Rockwell Scientific Imaging Sensors: ProCam-HD[tm] CMOS Imaging System-on-Chip for HDTV
(This has nothing to do with SIGGRAPH 2002-- it's something I found looking for CMOS info.)

3Q Technologies showed a fascinating image-based 3D scanner on the Exhibition floor and in the Studio area. Three cameras and one strobe per scan unit capture a model in 2ms.
It operates on a FireWire bus and multiple scanners can be chained for wide coverage. The custom software processes the images after capture, producing a 3D model without holes or spikes-- amazing accuracy and low scan time (though post processing from 2 units took maybe 15s). Multiple simultaneous datasets are merged automatically based on units' calibrated relative positions.
Here's a medical installation with four scan heads built into the console-- scan heads themselves looked to be ~3"x15"x12" (WxHxD).

Introduction to MegaWave2 , "a software environment designed to help people to write algorithms on signal processing and image analysis."
"Created in 1993 by Jacques Froment at the CEREMADE, University of Paris 9 Dauphine, it is now supported by the CMLA, a laboratory of mathematics of the Ecole Normale Supérieure de Cachan."
