AR Sudoku Solver

AR Sudoku Solver


The AR (Augmented Reality) Sudoku Solver is a tech demo that uses the phone's camera to find sudoku grids, solve them and project the results back into the picture.
The program expects the grid to be freestanding, flat and not manually filled.
Best results are achieved in good lightning conditions. The solver does not try to solve grids with less than 20 symbols (not restricted to numbers). All symbols must appear at least once.
Use the volume keys to toggle debug visualizations.

This is not a game, just a tech demo without any practical application that I know of.

Recent changes:
Completely rewrote the image capture part, processing remains unchanged. So far tested with Nexus S and Nexus One. I hope that this will make it work on Droid phones and the new Samsung Galaxy S2, but I have no test devices available, so it is all guess-work. Please let me know through comments if it improves/deteriorates compatibity.

Just red On my Htc one m8 it only shows shades of red through the camera. Thats all there is. The screen freezes like it is supposed to when you tap it with 2 fingers, but it just sits there.

Impresive Worked well when looking at my computer screen - and I know that processing screens sometimes messes up programs that are made for paper! Nice! :)
