Rotated iou loss

WebSep 20, 2024 · This topic isn’t strictly related to pytorch, but to computer vision. The 2D bounding box intersection over union (IOU) is relatively straightforward to calculate for a ground truth bounding box versus a model output, and thus translates neatly into a loss function. For 3D object detections, it would be nice to extend the IOU concept into 3D. …
