Abstract: Three image similarity algorithms based on hash, including average hash, perceptual hash and difference hash, are studied. Effects and performances of the hash algorithms for the three images are revealed comprehensively, both from the theoretical and experimental perspectives, and corresponding experimental data are provided for future references on proper selection of algorithms in different occasions.

Key words: Average Hash, Perceptual Hash, Difference Hash, image similarity
