Now, I am implementing rotated iou loss which is used for some works on oriented object detection.
But to compute intersection of two rotated boxes, it must use convex hull algorithm including sorting process.
But, to my knowledge, sorting is not differentiable.
Is that possible to implement rotated IoU Loss?
You can find a example of cuda implementation on https://github.com/facebookresearch/detectron2/blob/master/detectron2/layers/csrc/box_iou_rotated/box_iou_rotated_utils.h 13 .
