WebApr 9, 2024 · They will be removed after non-maximum suppression (NMS) processing. Hamid put forward the idea of generalized intersection over union, introducing the smallest bounding rectangle of the predicted box and the actual box on the basis of the IoU. The predicted boxes will move towards the object box given the introduction of penalty terms. WebAbstract: Intersection over Union (IoU) is the most popular evaluation metric used in the object detection benchmarks. However, there is a gap between optimizing the commonly used distance losses for regressing the parameters of a bounding box and maximizing this metric value. The optimal objective for a metric is the metric itself. trezor with metamaskhttp://proceedings.mlr.press/v139/yu21e/yu21e.pdf trez pro ortho

"Webnon-overlapping cases of two boxes can be better evaluated. Zheng et al. (2024) further proposed a distance-based IoU where the distance between two boxes is explicitly com-puted, and a complete IoU where the ratios of the box is additionally involved to constraint on the optimization.
