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.

Doesn't work Tried various modes, none seem to be able to pick it up off a screen. Shame too, since it works find on pages.

Good clean app, no requirements that the app have access to phone identity or other stuff apps have no business knowing. Has to be used on a clean grid, no scribblings. When the app gets the solution, the screen goes from red to white with the solution superimposed over it. Used my LG phone on a 9x9 grid, might have worked better if the lighting was better. Wish there was a way to save the solution other than freezing the screen hence the 4 stars
