This is a simple CLI tool that can compute hashes of jpg, png, webp and gif as well as compare images.
Currently the following algorithms are supported:
- Average Hashing (aHash)
- Block Hashing (bHash)
- ColorMoment Hashing (cmHash)
- Difference Hashing (dHash)
- Median Hashing (mHash)
- Perceptual Hashing (pHash)
- Wavelet Hashing (wHash)
There is an quick and dirty GUI implementation that works but is not covered with unit tests and refactored.
Hashing an image is can be done using the following command.
imghash get phash image.png
$ 00000e5e7e7f3d00%With the the format flag, binary output format can be selected.
imghash get --f binary phash image.png
$ 0000000000000000000011100101111001111110011111110011110100000000%Images can be compared using the following command
imghash compare phash image_a.png image_b.png
$ 0.91%
