And there are only two tracking hyper-parameters: the displacement and size smooth weights, making our tracker more robust to different challenging scenes.
Web3 aug. 2024 · IoU Aware The PP-YOLO network adds a prediction branch to predict the model's estimated IOU with a given object. Including this IoU awareness when making the decision to predict an object or not improves performance. Grid Sensitivity The old YOLO models do not do a good job of making predictions right around the boundaries of anchor … Webproposed. IoU-Net [10] adopts an additional network to predict the IoU and uses it to rank bounding boxes in NMS, but it still selects the classification score as the final detec-tion score.
