WebIntersection over Union (IoU) To train an object detection model, usually, there are 2 inputs: An image. Ground-truth bounding boxes for each object in the image. The model predicts the bounding boxes of the detected objects. It is expected that the predicted box will not match exactly the ground-truth box. The next figure shows a cat image. WebIoU is the area of overlap between the predicted segmentation and the ground truth divided by the area of union between the predicted segmentation and the ground truth. For binary (two classes) or multi-class segmentation, the mean IoU of the image is calculated by taking the IoU of each class and averaging them.
