Optimization for Arbitrary-Oriented Object Detection via Representation Invariance Loss
Optimization for Arbitrary-Oriented Object Detection via Representation Invariance Loss
Arbitrary-oriented objects exist widely in natural scenes, and thus the oriented object detection has received extensive attention in recent years. The mainstream rotation detectors use oriented bounding boxes (OBB) or quadrilateral bounding boxes (QBB) to represent the rotating objects. However, these methods suffer from the representation ambiguity for oriented object …
