Witryna15 sty 2024 · As of 2024, there's no need to implement your own IoU, as torchmetrics comes equipped with it - here's the link . It is named torchmetrics.JaccardIndex (previously torchmetrics.IoU) and calculates what you want. It works with PyTorch and PyTorch Lightning, also with distributed training. From the documentation: Witryna下面就简要介绍倾斜矩形框IOU的计算方法。 其算法流程大致如下： 给定两个倾斜的矩形 R_i, R_j 1. 首先设置点集 PSet ； 2. 将两个矩形的交点均加入至 PSet 中； 3. 接着将矩形 R_i 包含在 R_j 中的顶点加入至 PSet 中； 4. 同样，将矩形 R_j 包含在 R_i 中的顶点加入至 PSet 中； 5. 将点集 PSet 中的点进行三角化，可排成逆时针，计算面积 Area (I) …

In 2D, IoU is commonly applied to axis-aligned boxes, namely boxes with edges parallel to the image axis. In 3D, boxes are usually not axis aligned and can be oriented in any way in the world. shopping in socorro nm
