Bounding box loss
WebJan 24, 2024 · The loss function for bounding box regression (BBR) is essential to object detection. Its good definition will bring significant performance improvement to the model. Most existing works assume that the examples in the training data are high-quality and focus on strengthening the fitting ability of BBR loss. If we blindly strengthen BBR on low … WebJun 4, 2024 · Basically, it is not enough to just look at the overlap, because in the event of no overlap, you also want to look at how close the box was to the ground truth box and encourage the network to pull over the …

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. In the case of axis … WebA bounding box (Axis-Aligned Bounding Box and Oriented Bounding Box) is an automatically-created invisible box that defines the rough size of an entity. Its purpose is …
WebJan 20, 2024 · Download PDF Abstract: In object detection, bounding box regression (BBR) is a crucial step that determines the object localization performance. However, we find that most previous loss functions for BBR have two main drawbacks: (i) Both $\ell_n$-norm and IOU-based loss functions are inefficient to depict the objective of BBR, which …
