Note: "SUDOKU" is a registered trademark of NIKOLI Co., Ltd. (Japan) %%%%% SHORT EXPLANATION %%%%% Connect a web camera, confirm settings in sudokuvideo_fn.m, then run >> sudokuvideo_fn.m and point the camera at a sudoku puzzle. Run sampleprocess.m in cell mode to see the algorithm. %%%%% LONG EXPLANATION %%%%% What this demo does: 1. This attempts to identify the numbers in a sudoku puzzle using video input, and then solves the solution. 2. Optionally, the solution may be overlayed on the original video. What you will need: 1. A plain web camera that does not have a lot of noise. 2. A well focused image. 3. Decent lighting, with no large shadows on the image. What you need to do: First confim that you can solve puzzles: >> edit SUDOKU_PUZZLE1.txt >> mysudokusolver SUDOKU_PUZZLE1.txt Then do it using video: There are some parameters that need to be tuned in sudokuvideo_fn.m (see lines 3-18) Then run >>sudokuvideo_fn.m Stop it using control-c, or close the figure. If you get an out of memory error, run imaqreset. Notes: This will not work with every puzzle out there. It relies on the external box being very distinct, and the numbers having a particular type of font. You may need to do some experimenting to find one that works well. The MathWorks News&Notes from Nov 2009 with Cleve's Corner: MATLAB and Sudoku seems to work ok. File list: 1. sudokuvideo_fn.m: The main file which reads and preprocesses the video input. 2. identifynumbers_fun.m: The file which tries to find the location and value of numbers in the puzzle, by comparing to template data. 2. drawgraph.m: This receives a matrix M, calls sudoku_solver, and displays the solution in a table. 4. sudoku_solver.m: This recieves a matrix M, and calculates the Sudoku solution. 5. solution2image.m: This makes the overlay image of from the solution 6. sudoku_fn_trace.m: This takes the image from solution2image, and overlays it on the original video 7. TEMPLATEDATA.mat: This is a file that has sample numbers
