I want to train a model that should predict if a given signature is a genuine or a forged one. The model should take two images as input. One is the real signature, and the other is to be predicted.
Is there a way to check, how similar the two signatures are?
You can get an expert opinion from a graphologist. Graphology is the science of handwriting. A graphologist will be able to identify a fake signature after verification with an original.
Hello, When I was an intern in Bank, I was instructed to measure the similarity at least 3 words. Another thing is the way words moving forward. Because signatures has its own art. We had to measure the 3 words and the art also. But noted that, if someone is highly capable of doing the copy, I think we can't catch. But we have also suggested that maximum people give their signatures a little ups and downs, but still some people have perfect lining. But when we see the perfect lining tries to recheck with other sensitive details (details varies depends on place and country). I hope it helps. Thank you.
