Web24 jul. 2024 · Intersection over union (IoU) is known to be a good metric for measuring overlap between two bounding boxes or masks. Image is created by Oleksii Sheremet with Microsoft Visio. If the prediction is completely correct, IoU = 1. The lower the IoU, the worse the prediction result. Web24 aug. 2024 · Intersection over Union (IoU) is used when calculating mAP. 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.
