Dynamsoft Barcode Reader SDK allows developers to customize algorithm parameters against different barcode scanning scenarios. There are some pre-configured parameter templates for decoding performance. No matter you pursue ultimate decoding speed, ultimate decoding accuracy, or the tradeoff between speed and accuracy, there is always an appropriate one. Since the parameters...

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...

In my previous article, I shared how to integrate Dynamsoft Barcode Reader to LabelImg for annotating barcode objects. It is time to take a further step to make some custom models for barcodes. In this article, I will go through the process that I used Darknet to train YOLO v3...

LabelImg is a free and open-source image annotation tool written in Python and Qt5. It supports Pascal VOC format and Yolo format that are commonly adopted by mainstream machine learning frameworks. If you are interested in barcode object detection, you can use the tool to annotate different barcode symbologies with...
