License plate detection using YOLO v4

Abstract

Automatic License Plate Recognition (ALPR) is a sizzling topic in the disciplines of intelligent transportation systems and image recognition. The real-time object detector YOLO (You Only Look Once) - darknet deep learning framework is used in this article to detect car number plates in parking lots in real time. The YOLOv4 deep learning technique was utilized in this proposed strategy to automatically recognize a car's number plate from a video stream. An OCR technique is applied to extract the number from the image of the number plate. The system detects license plates with an accuracy of around 89%.
