ESupervisedSegmenterMetrics::GetIntersectionOverUnion
Intersection over union.
The intersection over union if the ratio between the number of correctly classified pixels from the given label to the total number of pixels that belongs to that label or are predicted as being from that label.
Assuming that the given label is the positive class, the intersection over union is expressed as IOU = TP / (TP + FP + FN) where TP is the number of true positive, FP the number of false positive (pixels that belongs to label but are not predicted as label) and FN the number of false negative (pixels predicted as label but that do not belong to label).

Parameters
label
Label
Remarks
The intersection over union is also called the Jaccard index.
