Dear Teja,
could you tell me how can I change all this to be able to recognise numbers on a playing cards?
I can see you got a data template for the digits. How could I tell it to scan a number and tell me which is it just on a screen? Is it difficult?

Updates
24 Feb 2011

There was an insidious bug in
sudoku_solver.m

That is now fixed.

28 Feb 2011

Added a notice in the description regarding the fact that "Sudoku" is a trademark in Japan.

03 Mar 2011

Added a missing file (TEMPLATEDATA)

11 Apr 2012

Due to a few changes regarding MATLAB math in R2012a, this demo needed some updating. Namely, since MEDIAN now errors with UINT8 input, a small fix we needed to correct this. This updated file should now work with R2012a.
