Computing confidence score using probability and IoU

I am trying to fuse two detections with the help of a probability model and, to know that both detections belong to the same object, I use the Intersection over Union (IoU) score. So, the confidence-...

Why is it called "area of union" when calculating the Intersection over Union?

When calculating the Intersection Over Union the following explanation is widely used. (Source: A Survey on Performance Metrics for Object-Detection Algorithms, by Padilla et al. 2020) The image and ...

Can a GIoU loss (generalized intersection over union) be used after an STN module (spatial transformer network)?

I have a model that uses an STN module for number detection and Mean Squared Error loss. But I would like to replace it for GIoU, because MSE doesn't take into account how much of the target area has ...

How are IOUs for ground truth boxes in YOLO calculated?

I know how IOU works during detection. However, while preparing targets from ground-truth for training, how is the IOU between a given object and all anchor boxes calculated? Is the ground truth ...
