On a related note, I'm curious if anyone has run across a good set of algorithms (or hopefully a library) for doing naive image classification. I'm looking for something that can classify images into something similar to the broad categories that Google image search has (Face, Photo, Clip Art, Line Drawing, etc.). --Paul
