Signature recognition/detection from a digital document or scanned Image

Hi Champions, I am trying to build an utility which will recognize signature from a Digital document or Scanned Image. I am trying various ML libraries but I feel OpenCV can be perfect for this. Can anyone guide me on this topic? Thanks a lot in Advance.

if you need to extract the signature first then take a look at this repo GitHub - ahmetozlu/signature_extractor: A super lightweight image processing algorithm for detection and extraction of overlapped handwritten signatures on scanned documents using OpenCV and scikit-image.
