Web30 jul. 2024 · Using Intersection over Union loss to improve Binary Image Segmentation. In semantic segmentation tasks the Jaccard Index, or Intersection over Union (IoU), is often used as a measure of success. While this measure is more representative than per-pixel … WebIntersection Over Union (IOU) is a measure based on Jaccard Index that evaluates the overlap between two bounding boxes. It requires a ground truth bounding box and a predicted bounding box . By applying the IOU we can tell if a detection is valid (True Positive) or not (False Positive).
