Dynamic Anchor Learning for Arbitrary-Oriented Object Detection
Dynamic Anchor Learning for Arbitrary-Oriented Object Detection
Arbitrary-oriented objects widely appear in natural scenes, aerial photographs, remote sensing images, etc., and thus arbitrary-oriented object detection has received considerable attention. Many current rotation detectors use plenty of anchors with different orientations to achieve spatial alignment with ground truth boxes. Intersection-over-Union (IoU) is then applied to sample the positive …
