As an example, the … Web27 mei 2024 · If IoU satisfies the threshold, we assume the prediction is correct. For example, if the IoU threshold is 0.5, any prediction with an IoU of 0.5 or more is correct. So, this IoU threshold is a hyperparameter that affects how many correct and incorrect predictions the model produces.
