In the previous article, we’ve created a React Native Vision Camera frame processor plugin for Dynamsoft Barcode Reader (DBR). Let’s continue to create the frame processor plugin for iOS. This article is Part 2 in a 3-Part Series. Part 1 - Build a React Native Vision Camera Frame Processor Plugin...

The previous popular react-native-camera project is now deprecated in favor of react-native-vision-camera. Vision Camera offers new APIs, better performance, improved stability and more features. It has a feature called Frame processors, which makes it easy to integrate extra image processing abilities. We are going to create a frame processor plugin...

Creating a virtual camera is useful to test camera-dependent applications. We can use static images or videos as the image source for the virtual camera to test things like barcode reading, text recognition, and document scanning. Adopting pyvirtualcam Creating a virtual camera involves complex driver development. Fortunately, there have already...

As the dominant JavaScript document scanning SDK, Dynamic Web TWAIN has recently adopted WebAssembly as the new weapon. From version 17.2, Dynamic Web TWAIN does not only support cross-platform (Windows, Linux, and macOS) scanner access, but also allows developers to utilize desktop and mobile cameras to scan documents using JavaScript....

A week ago, I made an experiment to test the QR code detection performance with YOLOv4 on Android. The inference time of running the YOLOv4 model on CPU is more than 100ms, which does not reach my expectation. Since Android Neural Networks API (NNAPI) provides hardware acceleration for TensorFlow Lite...

In my previous article, I demonstrated how to implement a simple Android QR code scanner. Based on the codebase, I am going to do something more interesting - integrate the YOLOv4 tiny model that I trained for QR code detection into the Android project. Is YOLO tiny competent for real-time...

Note: This article talks about how to build a QR code scanner native UI component for React Native. If you need to use Dynamsoft Barcode Reader in a React Native project for production, please use the official Dynamsoft Capture Vision SDK. React Native is an open-source UI software framework made...
