WebAug 24, 2024 · It is a number from 0 to 1 that specifies the amount of overlap between the predicted and ground truth bounding box. an IoU of 0 means that there is no overlap between the boxes an IoU of 1 means that the union of the boxes is the same as their overlap indicating that they are completely overlapping ( source)
WebJan 6, 2024 · An IoU of 1 implies that predicted and the ground-truth bounding boxes perfectly overlap. You can set a threshold value for the IoU to determine if the object detection is valid or not not. Let’s say you set IoU to 0.5, in that case. if IoU ≥0.5, classify the object detection as True Positive(TP) shops at legacy apartmentsWebJun 15, 2024 · A bounding box can be proposed over each cell center.
