[OSM-dev] [GSoC] Automatic Street-Sign Detection and Reading - was: [GSoC] A GPX photo stamper.

I just posted my proposal to the wiki:
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? :)

contrast or bad color representation might be a problem though.

Thanks for the hint! - More robustness to differing angles sounds like
something we could definitely use. I've added the link to my references and
will look into it in more detail.
