WebIntersect over Union (IoU) is a metric that allows us to evaluate how similar our predicted bounding box is to the ground truth bounding box. The idea is that we want to compare the ratio of the area where the two boxes overlap to the total combined area of the two boxes. The formula for calculating IoU is as follows.

WebIoU to construct a mini-batch Soft IoU loss function. The major contributions of this paper are summarized as follows: (1)We extend the IoU loss to multi-class segmentation tasks. (2)We propose mini-batch Soft IoU strategy based on this, which guarantees that the number of categories is at least equal to the batch size in every single mini-batch.
