phash: Haskell bindings to pHash, the open source perceptual hash library

PHash is a library for generating perceptual hashes of media files. These bindings currently only support images. You can compare these hashes to detect visually similar images.

Installation Notes

Note that this library does not come bundled with the source code for pHash. You must install that yourself. Your package manager may have it available as libphash. If that is not available, you can install it from source from


import Data.PHash

main = do
  Just h1 = imageHash "somefile.jpg"
  print h1
  print =<< imagesSimilar "somefile.jpg" "similarfile.jpg" reasonableThreshold
  where reasonableThreshold = 15
