Weighted Intersection over Union (wIoU) is a metric for evaluating image segmentation results, computed by applying per-pixel weights to the standard IoU. It gives greater weight to errors near object boundaries or in important regions, aiming to capture differences in boundary quality that IoU and mIoU miss because they only look at the overlap of whole regions. It was proposed as a new evaluation metric in an arXiv paper (2107.09858).
