Bounding box ground truth

WebMar 24, 2024 · Given a ground-truth bounding box and a detected bounding box, we compute the IoU as the ratio of the overlap and union areas: Here are some examples of different IoU values: The IoU can have any value between 0 and 1. If two boxes do not intersect, the IoU is 0. On the other hand, if they completely overlap, the intersection and … WebMar 2, 2024 · Callout: Intersection over Union (IoU) is measured as the area of overlap between your model’s prediction and the ground truth, divided by their union.IoU tells you much of the total area of an object your predictions tend to cover.. Two perfectly overlapping annotations have an IoU of 1.00. Pay attention to box size variation. Variations in box …
