Witryna2 cze 2024 · The Intersection over Union (IoU) metric, also referred to as the Jaccard index, is essentially a method used usually to quantify the percent overlap between the ground truth BBox (Bounding Box) and the prediction BBox. However, in NMS, we find IoU between two predictions BBoxes instead. WitrynaRotate iou: A new iou-based loss function for orientation-aware object detection. In 2024 IEEE International Conference on Computer Vision Workshops (ICCVW), pages 0–0. IEEE, 2024. [11] Yuxuan Zhang, Shuyang Sun, Huchuan Lu, and Meng Wang.
