Just a quick note to tell that I've updated my project proposal on the wiki:
Since SIFT probably isn't going to work, we need something else. The
color-histogram-matching might work. While going through my computer-vision
book searching for ideas I found a number of other ideas (structural pattern
recognition, texture-based features, more segmentation-oriented methods).
More details and references in the proposal.
I mean, come on, one of these methods must be able to detect street signs.
