Source description
This version of YOLO11-OBB (Oriented Bounding Box) has been converted to run on the Axera NPU using w8a16 quantization. It is optimized for detecting rotated objects such as ships, harbors, vehicles, and other DOTA-style targets with oriented bounding boxes.
Compatible with Pulsar2 version: 6.0.
