How to Detect and Decode QR Code with YOLO, OpenCV, and Dynamsoft Barcode Reader

In the past two weeks, I trained a custom YOLOv3 model for QR code detection and tested it with Darknet. In this article, I will use OpenCV’s DNN (Deep Neural Network) module to load the YOLO model for making detection from static images and real-time camera video stream. Besides, I will use Dynamsoft Barcode Reader to decode QR codes from the regions detected by YOLO.
