Web20 sep. 2024 · IoU (Intersection over Union) To decide whether a prediction is correct w.r.t to an object or not, IoU or Jaccard Index is used. It is defines as the intersection b/w the predicted bbox and actual bbox divided by their union. A prediction is considered to be True Positive if IoU > threshold, and False Positive if IoU < threshold. Web27 mei 2024 · If IoU is 1, the prediction perfectly matches the ground truth. If IoU is 0, there is no overlap. If you’re curious, you may want to refer to another article that I explain how to calculate IoU. As I said, IoU rarely becomes 1, so we set a threshold for IoU. If IoU satisfies the threshold, we assume the prediction is correct.
