Image hash for fast similarity search
find . -name \*.png | store.py
For now, only bitmap images (that are accessible via PILLOW) can be specified.
query.py filename.png
query.py --level 6 filename.png
The similarity level is between 1 (lowest resolution (2x2), 1 bit in brightness level) and 8 (highest resolution (256x256), 8 bits in brightness level).
