Let's not do that again, okay? Little Miles gets hung up in a cat door. [Quicktime requiring ActiveX] via
The Flo Control Project is a test project for image recognition algorithms developed by Quantum Picture. Basically, they rigged a home computer to control their cat door using image recognition software so that it would only allow cats to enter the house (and not skunks or raccoons), and then only if the cat wasn't carrying prey items (to play with in the comfort of the living room). The newest version of the experiment can differentiate between the two cats currently living in the house. Interesting stuff, not least because many people couldn't tell two cats apart simply by looking at their profiles. I suspect there are some wide-ranging non-feline applications as well.
