Perceptual Hash
===============

[](#perceptual-hash)

This library is a rewrite of the perceptual hash implementation by Anatoly Pashin (@b1rdex) for the jenssegers/imagehash library made by Jens Segers (@jenssegers). It provides a way to generate perceptual hashes for images using PHP.

Installation
------------

[](#installation)

To install the library, use Composer:

```
composer require sidus/perceptual-hash
```

Usage
-----

[](#usage)

Here is a simple example of how to generate perceptual hashes for images:

```
$manager = new \Intervention\Image\ImageManager($driver);
$image = $manager->make($imagePath);
$hash = PerceptualHash::hash($image);
```

And to compare two hashes:

```
$distance = PerceptualHash::distance($hash1, $hash2);
```
