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...

Although almost every Android phone is equipped with cameras, some Android devices, like TV boxes and kiosks, may not have cameras built-in. An easy way to add extra camera functionality to these devices is by connecting with a USB camera if they support USB-OTG. Starting from Android 9, the Android...

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...
