  Img_hash |
  ImgHashBase | The base class for image hash algorithms
  MarrHildrethHash | Marr-Hildreth Operator Based Hash, slowest but more discriminative.
  PHash | pHash Slower than average_hash, but tolerant of minor modifications This algorithm can combat more variation than averageHash, for more details please refer to CITE: lookslikeit
