Get all the descriptors from the image (say, N of them). Each descriptor is a vector of 128 numbers (you can convert them to be integers between 0 and 255). So you have a set of N*128 integers. Just write them one after another into a string and use that as a hash value.

Analysis, portable implementation, and optimization of a perceptual image hashing algorithm (incl. an internal … WebAverage hashing; Perceptual hashing; Difference hashing; Wavelet hashing; HSV color hashing (colorhash) Crop-resistant hashing _ _ Rationale. Image hashes tell whether two images look nearly identical. This is different from cryptographic hashing algorithms (like MD5, SHA-1) where tiny changes in the image give completely different hashes.

WebWhen the hash size is increased to 16 (256-bits), none of the hash functions resulted in collisions, but near-identical images were detected for average hash and wavelet hash. Both perceptual hash and differential hash showed no collisions nor near-identical images. Here again, the perceptual hash is less conservative.
