I'm not sure whether this is very suitable for a webapp since it might
require quite some computation, and will generally operate on databases of
pictures that might be a pain to upload. It's certainly possible though.
Maybe we should think about a platform which allows it to be used both
locally and as a webapp.

Which.. I of course read minutes after the application deadline expiring. ;)
- No sweat, I'll read up on the subject a bit more and keep on adding new
ideas to the proposal on the wiki.

SIFT *might* be able to do some of it's work on features typically present
in street-signs. For example: Many street signs have a white bar around
Otherwise we will have to trust on the color-histogram matching, and I'll
think about other feature detectors to use as well. (suggestions welcome
