php-ffi experiment
=========
php interface to the lib-darknet for object detection.
Php7.4+ is required

Install
---------
composer require ghostjat/darknet

Description
-----------
[lib-darknet](https://github.com/pjreddie/darknet)

# Darknet #
Darknet is an open source neural network framework written in C and CUDA. It is fast, easy to install, and supports CPU and GPU computation.

* It offers a simple API.
* High performance, due to the fact that it uses native interface elements.
* Fast learning by the user, due to the simplicity of its API.
# yolo v2, v3, v4 #

If running on cpu you may use FASTEST cfg & weight for real time object detection on MS COCO dataset.
```php

require '../vendor/autoload.php';

use darknet\core;
$dn = new core(core::YOLOFASTEST);
```

require '../vendor/autoload.php';

use darknet\core;
$lib = '/home/ghost/bin/c-lib/darknet/data/';
$img = ['eagle.jpg','giraffe.jpg','horses.jpg','person.jpg','kite.jpg'];
$dn = new core();
foreach ($img as $value) {
    $dn->detect($lib.$value);
}
