YOLO DNNs {#tutorial_dnn_yolo}
===============================
Introduction
------------
In this text you will learn how to use opencv_dnn module using yolo_object_detection (Sample of using OpenCV dnn module in real time with device capture, video and image).
We will demonstrate results of this example on the following picture.
