Excellent demos. One suggestion for the creator/maintainer of the demo pages: It would be nice if the imageDiff demo had two pre-made images to do a diff on.

Excellent demos. One suggestion for the creator/maintainer of the demo pages: It would be nice if the imageDiff demo had two pre-made images to do a diff on. I spent a few minutes taking a shot with my webcam and then another with my had in the scene just to see how the static diff worked. Pre-loading a shot of a background and one with something added to the image would be a nice start to the demo instead of making the user drag/drop their own images. As a totally unrelated note, if this interests you, you might also get a kick out of coherent change detection (CCD) which works on synthetic aperture radar (SAR) images: http://defense-update.com/features/du-2-05/sensor-5.htm http://defense-update.com/features/du-2-05/sensor-5.htm. CCD has been used by military intelligence for a while now, and although a lot of the cool stuff is classified, the basics of the technique are unclassified and kind of cool.
