ImageHashCache
A image hashing library written in Python. ImageHashCache supports:
- average hashing (aHash)
- perception hashing (pHash)
- difference hashing (dHash)
- caching resized images
Requirements
Based on PIL/Pillow Image, numpy and scipy.fftpack (for pHash) Easy installation through pypi.
Basic usage
>>> from PIL import Image >>> import imagehash >>> hash = imagehash.average_hash(Image.open('test.png')) >>> print(hash) d879f8f89b1bbf >>> otherhash = imagehash.average_hash(Image.open('other.bmp')) >>> print(otherhash) ffff3720200ffff >>> print(hash == otherhash) False >>> print(hash - otherhash) 36
The demo script find_similar_images illustrates how to find similar images in a directory.
