Not a pair. The number of possible perturbations of each example image in deep learning are enormous. This blithe quote implies that a hash code somehow can provide a flexible match against the billions of perturbations even a single image can undergo. It's a specious claim, and intended to cow anyone from disbelieving in the effectiveness of such a brute force match model.
