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.

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

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