Quickly find visually similar images
Project description
libpuzzle
=========
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.
Installation:
pip install libpuzzle
Usage::
from libpuzzle import Puzzle, SIMILARITY_THRESHOLD
puzzle = Puzzle()
sign1 = puzzle.from_filename('img1.jpg')
sign2 = puzzle.from_filename('img2.png')
distance = sign1.distance(sign2)
if distance <= SIMILARITY_THRESHOLD:
print('images are propably the same')
API:
.. py:data:: SIMILARITY_THRESHOLD
.. py:data:: SIMILARITY_HIGH_THRESHOLD
.. py:data:: SIMILARITY_LOW_THRESHOLD
.. py:data:: SIMILARITY_LOWER_THRESHOLD
.. py:class:: Puzzle
.. py:attribute:: max_width
.. py:attribute:: max_height
.. py:attribute:: lambdas
.. py:attribute:: noise_cutoff
.. py:attribute:: p_ratio
.. py:attribute:: contrast_barrier_for_cropping
.. py:attribute:: max_cropping_ratio
.. py:attribute:: autocrop
.. py:method:: from_filename(filename) -> Signature
.. py:method:: from_signature(sign) -> CompressedSignature
.. py:method:: from_signature(sign) -> Signature
.. py:method:: vector_normalized_distance(sign1, sign2) -> bool
.. py:class:: Signature
.. py:class:: CompressedSignature
.. py:exception:: PuzzleError
