This looks nice, and seems to support the most common methods for fingerprinting/hashing. This comes with some heavy dependencies, though (which is reasonable):

This looks nice, and seems to support the most common methods for fingerprinting/hashing. This comes with some heavy dependencies, though (which is reasonable): install_requires=[ 'numpy==1.16.3', 'Pillow==6.0.0', 'PyWavelets==1.0.3', 'scipy==1.2.1', 'tensorflow==2.0.0', 'tqdm==4.35.0', 'scikit-learn==0.21.2', 'matplotlib==3.1.1', ], A while ago, I asked about sth like this (or more about the underlying methods) here on SO: https://stackoverflow.com/questions/4196453/simple-and-fast-method-to-compare-images-for-similarity https://stackoverflow.com/questions/4196453/simple-and-fast-... There are some interesting discussions. (Nowadays, such a question would have been closed...)
