How to find a pattern in an image
-
Hi all. I need to find a signature block in a scanned document. I can create the document so I can put a box around the signature or mark it in some way. I just don't know how to find it. I don't think I can depend on it always being in the same spot. Any ideas?

Depends on what a 'signature block' is. Obviously, because it's scanned, you can't depend on it being pixel for pixel exactly what you expect, or even to be rotated 100% correctly. You'll need to do some fairly complex pattern matching. Edge detection would be a good place to start, to simplify the image you're dealing with, assuming this won't lose detail that you need to find. Christian Graus - Microsoft MVP - C++
