E.g. phash from https://cran.r-project.org/web/packages/OpenImageR/OpenImageR.pdf

It's certainly simpler than having the custom signatures, but is it faster, and is it more accurate?

Hashing will give a vastly faster match (no need to calculate correlation matrix), but only yes/no, so what happens to false negatives?
