Very nice work.
Character recognition might be somewhat more robust if a thinning operation, than look for line segments and relative angles/breaks (that's how people recognize numbers).

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?

Brilliant work! One of the best!
