+  IoU 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.
