I have two cropped images of a signature from bank cheque. What is the best way to compare the two images.
Pls some one help me with the code.
Thanks much.

Alex, That method is extremely primitive and most likely won't work for more than a few signatures (a very tiny database). I suggest you look to published papers for successful algorithms:
23.4.6.4.3 Signature Recognition, Surveys, Analysis, Comparisons

Don't think code, until you have to idea in place. Do you have any specific ways you want it to work? Or any thoughts on it?

Supposing that the signature is more or less in the same place every time, how about some sort of cross correlation of the signature area?
