A simple solution to incorporate object localization into conventional computer vision object detection algorithms.
IDEA: There aren't that many open source real-time 3D object detection. This is an example of using "more popular" 2D object detection and then localize it with a few feature points. It uses recently released Barracuda for object detection and ARFoundation for AR. It works both on iOS and Android devices.
Currently supports tiny Yolo2 and 3 and 4.
