 ## Overview
 
-This is a ROS package developed for object detection in camera images. You only look once (YOLO) is a state-of-the-art, real-time object detection system. In the following ROS package you are able to use YOLO (V3) on GPU and CPU. The pre-trained model of the convolutional neural network is able to detect pre-trained classes including the data set from VOC and COCO, or you can also create a network with your own detection objects. For more information about YOLO, Darknet, available training data and training YOLO see the following link: [YOLO: Real-Time Object Detection](http://pjreddie.com/darknet/yolo/).

-The YOLO packages have been tested under ROS Noetic and Ubuntu 20.04 (Please check the branches for melodic, foxy, and ROS2 versions). This is research code, expect that it changes often and any fitness for a particular purpose is disclaimed.
