kodus/image-hash
================

[](#kodusimage-hash)

This library implements the aHash, dHash and pHash image-hashing algorithms as described in [this article](http://www.hackerfactor.com/blog/?/archives/529-Kind-of-Like-That.html).

It's based on [this implementation](http://jax-work-archive.blogspot.dk/2013/05/php-ahash-phash-dhash.html)but with a loader-abstraction for GD and Imagick support, added tests, and a benchmark.

Usage
-----

[](#usage)

To compare two images:

```
use Kodus\ImageHash\ImageHasher;

$hasher = new ImageHasher();

$a_hash = $hasher->pHash("path/to/image-a.jpg");
$b_hash = $hasher->pHash("path/to/image-b.jpg");

if ($hasher->getDistance($a_hash, $b_hash)
