Detecting objects using YOLO on Raspberry Pi 4

YOLO stands for you only look once. It is a fast image classification library that is optimized for GPU processing. YOLO tends to outperform all other computer vision libraries. In this recipe, we are going to implement a computer vision object detection using OpenCV's implementation of YOLO. In this example, we are going to use a pretrained model that has 40 common objects already trained.
