Is there a good algorithm to detect 2 matrix are similar

Question

I have two matrix like below (A) and (B) ↓

I want to know ,

1) Is the number (7,6) in (B) is also in (A)

2) Is B is 66%up like A .....

And ,how can I do that with CSharp?

Thanks for your advices.....

What do you mean by "66% like"? I understand that 100% like is identical, but how does that degrade? If I have a matrix that has ones where you have zeroes and zeroes where you have ones, how resembling are these? — zneak

I'm sorry for my bad english... I mean , A has 7 , 1 , 6 and B only has 7 , 6 , so there is 2/3 ~ 0.66 ...and also if the 7 in (B) is not completely...the result will less than 0.66 ... — shenhengbin

OCR (Optical Character Recognition) is a huge field - and not my field.

Neural networks are a potential solution depending on your situation. There is a C# solution on this Code Project page:
