EDIT: Parent edited his comment to clarify. I understand the point now. I'm wrong about similar images needing to have "similar" hashes. Those hashes either need to match exactly, or else not be considered at all. IGNORE THIS: I think that's the parent comment's point. These are definitely not cryptographic hashes, since they—by design and necessity—need to mirror hash similarity to the perceptual similarity of the input images.
