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 … WebFor a bounding box labeling job, Ground Truth calculates a confidence score per box. You can compare confidence scores within one image or across images for the same labeling type (human or auto). You can't compare confidence scores across labeling jobs.
