img_hash
Now builds on stable Rust! (But needs nightly to bench.)
A library for getting perceptual hash values of images.
Thanks to Dr. Neal Krawetz for the outlines of the Mean (aHash), Gradient (dHash), and DCT (pHash) perceptual hash algorithms:

Also provides an implementation of the Blockhash.io algorithm.
This crate can operate directly on buffers from the PistonDevelopers/image crate.
Usage
Add img_hash
to your Cargo.toml
:
[dependencies.img_hash]
version = "3.0"
Example program:
extern crate image;
extern crate img_hash;
use ;
Benchmarking
In order to build and test on Rust stable, the benchmarks have to be placed behind a feature gate. If you have Rust nightly installed and want to run benchmarks, use the following command:
cargo bench --features bench
