WebHowever, IoU is infeasible to optimize in the case of non-overlapping bounding boxes. Then Generalized IoU (GIoU) loss (Rezatofighi et al. 2024) addresses this weakness by in-troducing a generalized version as the new loss. After that, Distance IoU (DIoU) loss (Zheng et al. 2024) adds the nor-malized center distance between the predicted box ... Web前言. 在Unitbox [2]一文中，IoU Loss被提出用于替代传统的MSE或者Smooth L1损失函数，它们提出的动机是IoU是一个更能反馈检测效果的指标。. 这里要介绍的GIoU Loss [1] …

The text was updated successfully, but these errors were encountered: WebIntersection 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.
WebAug 20, 2024 · With a multinomial cross-entropy loss function, this yields okay-ish results, especially considering the sparse amount of training data I´m working with, with mIoU of 0.44: When I replace this with my dice loss implementation, however, the networks predicts way less smaller segmentations, which is contrary to my understanding of its theory.
