A Gentle Introduction to YOLO v4 for Object detection in Ubuntu 20.04

In this post, we are going to see the basics of object detection in the computer vision, basics of famous object detection system YOLO (You Only Look once), and the installation procedure of the latest YOLO v4 in Ubuntu. This post is indented for absolute beginners who don't have much idea on implementing an objection detection system in Ubuntu Before discussing the object detection concepts, it will be good to start with the following concepts in computer vision. Object classification: This technique predicts the probability of different object categories( car, dog, cat, etc.) in an image, it essentially answers the question "What is in the picture?". It can only predict one category for one image. Object localization: This method can predict the probability of an object in the image along with its location in the image. This technique basically answers "What is in the picture and where it is?".
