Webb2 juni 2024 · To achieve this, we create a mask using the criteria which elements in IoU have a value less than thresh_iou as those are the values we want to keep. For example, if IoU = [0.4, 0.6, 0.3] and thresh_iou = 0.5, then mask = IoU < thresh_iou will result in mask = [True, False, True]. highline ctclink mobileWebbStanford Method for Persistent Scatterers.
