Most definitely! - tnx.
Since we won't be using video, we can't use the tracking part. Looking at
the video's, I don't think the system will give a 'hit' for every picture we
throw at it, but it does seem to offer reasonable performance, and it's
interesting to see the methods that they've used to detect test. Added to
the proposal!

Note that for now I'm focusing on street-sign OCR (also to not thread on
other peoples toes), for which I think this might be relevant research.
During development, my focus will be on reusability, and many of the things
I produce should be directly applicable to the traffic-sign recognition
Since I was kinda hoping that you would be my mentor ;) - Please let me know
if you want me to take a different direction / focus more on generic sign
