I'm fond of Image Processing, MultiViewStereo, Structure From Motion.
I want to develop OpenSource for MultiViewStereo and Structure From Motion with clean implementation of State of the Art methods. For me a paper is nothing if it do not comes with an implementation or a test interface. Research is for going further and not trying to reproduce things that already exists...
