I am trying to compare the 3 fonts from the image. I want some algorithm witch will say 2 and 3 are matching fonts but 1 is not matching font. I have tried this approach using HuMoments, but it does not seem to work. https://stackoverflow.com/questions/56607680/font-matching-using-image-moments-in-opencv
Is there any other way to find how much similar one font is to the other from the images ?
