Generalized IoU for 2D and 3D
这里尝试同时记录两篇相关的论文,分别描述的Generalized 2D IoU 与Generalized 3D IoU,最终解决的都是在没有intersection的情况下得到一个对IoU的估计
Generalized Intersection over Union: A Metric and A Loss for Bounding Box Regression
这篇是CVPR使用Generalized 2D IoU的原文,至于是这个算法好,还是signed_iou效果好,有待测试
3D-GIoU: 3D Generalized Intersection over Union for Object Detection in Point Cloud
3D IoU的算法在这篇文章有详细描述
