Beyond Horizontal Paradigm: Circle Anchors for Oriented Object Detection

State-of-the-art oriented object detectors are predominantly built upon horizontal object detection paradigm, relying on horizontal anchors to generate oriented proposals or bounding boxes. However, these traditional horizontal anchor-based methods encounter the regression ambiguity problem, where d...
