This is a skeleton project that demonstrates how to implement a basic Android camera preview by using CameraX and Dynamsoft Camera Enhancer respectively. The project also features QR code scan. You can replace this part with other image processing code.
- Camera preview
- QR code scanning by Dynamsoft Barcode Reader
- Result overlay
- Auto-torch
- Zoom by fingers
- QR code detection by YOLO tiny
