Quickly find visually similar images

Project Description

Implements libpuzzle for python.

It is designed to quickly find visually similar images (GIF, PNG, JPG), even if they have been resized, recompressed, recolored or slightly modified.

Sample applications:

  • finding duplicate images in photo libraries
  • image classification
  • image search services
  • moderation (pictures sent by users on forums, wikis, blogs, etc). Pictures similar to other pictures that were previously banned can be signaled to moderators.

The library relies on the GD Library in order to load bitmap pictures.

On a debian server, installation would be:

$ apt -y install libpuzzle-dev libgd2-xpm-dev
$ pip install libpuzzle


from libpuzzle import Puzzle, SIMILARITY_THRESHOLD

puzzle = Puzzle()
sign1 = puzzle.from_filename('img1.jpg')
sign2 = puzzle.from_filename('img2.png')
distance = sign1.distance(sign2)
    print('images are propably the same')



class Puzzle:

    max_width  #

    max_height  #

    lambdas  #

    noise_cutoff  #

    p_ratio  #

    contrast_barrier_for_cropping  #

    max_cropping_ratio  #

    autocrop  #

    from_filename(filename) -> Signature
        # hydrate Signature from filename

    from_signature(sign) -> Signature
        # hydrate Signature from value

    from_compressed_signature(sign) -> Signature
        # hydrate Signature from compressed value

class Signature:
    # Implements signature

    value  # the value
    compressed  # the compressed value

    distance(signature) -> float
        # distance between 2 signatures

exception PuzzleError:
    # Raise when something went wrong
