I just posted my proposal to the wiki: http://wiki.openstreetmap.org/wiki/GSoC_Student_Applications_2009#Draft_application:_Automatic_Street-Sign_Detection_and_Reading. It might still have a few rough edges. Feedback is welcome!
A few specific questions: - Do you agree that part of the deliverables is to have the street-sign detector implemented in JOSM? Would this be the right place to implement this system? Are we even interested in implementing this system somewhere, or should it just be a proof-of-concept? - Would anybody be interested in mentoring this interesting project? Preferably someone with SIFT-experience, but I would be happy to work with anyone who's enthusiastic about this project. Stefan or Matt maybe? :) On Fri, Apr 3, 2009 at 1:05 PM, Tom Evans <[email protected]> wrote: > > If this could work off a straight-angle photo, but with only a > mobile phone camera, that could be pretty nice to work with. > > I don't really expect any problems with phone-cams. For most computer vision algorithms, the first step is to scale down the image anyway. Worse contrast or bad color representation might be a problem though.

I've added the link to my references and will look into it in more detail. ~ Tijs
