Using Computer Vision with Drones for Georeferencing
SUMMARY
A computer vision model can detect objects in drone footage but only tells you where something appears in a frame, not where it is on Earth. This tutorial shows how to combine detection output with the flight log from a DJI Mavic Air 2, converting pixel coordinates to latitude

Using Polygon Annotations for Object Detection in Computer Vision
SUMMARY
Polygon annotations improve object detection model training even when the model only outputs bounding boxes, because the extra shape data makes augmentations more accurate. Spatial transforms like rotation and cropping stay tightly fitted to the object with polygons, while bounding boxes pick up background pixels that dilute training signal.
