iPhone Sudoku Grab: How does it all work? on 2009-08-13
-
A good source to get started with is the OpenCV library which can be compiled on most platforms (including the iPhone). I wish I'd been aware of it before I started this project as it would have saved quite a bit of time.
One of the things that makes recognizing Sudoku puzzles an easier task than most image processing/recognition problem is that it is a highly constrained problem - a standard Sudoku puzzle is going to be a square grid and it will only contain the printed numbers 1-9.
These two points are very important. The first point - it's a square grid tells us what shape a puzzle is and what we should be looking for in an image. The second point - it will only contain the printed numbers 1-9 tells us that we aren't going to need a sophisticated OCR system. When we look at the problem there's nothing that jumps out and says "nobody has solved this before - it's probably really hard".
