Synopsis

imgHash :: (Ord e, Floating e, Array arr Y e, Array arr X e, Vector (Vector arr) Bool, Vector (Vector arr) e) => Image arr Y e -> Word64
fileHash :: FilePath -> IO (Either String Word64)
hammingDistance :: Bits a => a -> a -> Int

Documentation

imgHash :: (Ord e, Floating e, Array arr Y e, Array arr X e, Vector (Vector arr) Bool, Vector (Vector arr) e) => Image arr Y e -> Word64 Source #

DCT based hash. See Zauner.

It is suggested that you use this with the Repa backend.

fileHash :: FilePath -> IO (Either String Word64) Source #

hammingDistance :: Bits a => a -> a -> Int Source #
