Can someone please explain to me how this comparison would work? It seems so trivial to alter any image containing CP slightly such that its hash doesn't compare anymore?
- sneak 5y agoPerceptual hashes are not related to byte-level hashes.
- onepunchedman 5y agoYeh I must have ignored the "perceptual" part when I read it over
- dilap 5y agoConfusingly, it's a completely different use of the word "hash" See here: https://en.wikipedia.org/wiki/Perceptual_hashing https://en.wikipedia.org/wiki/Perceptual_hashing The goal of a perceptual hash is to generate a number that will be the same for all "similar" looking images. Think like what Shazam does, but in the visual domain.
