Hi, what is the design idea behind IoU metric implemented for point clouds? There is a threshold but the output IoU score increases when we decrease the threshold. Should not it be the opposite, since the intersection region would decrease when threshold is decreased?
Another thing: IoU is not consistent with F score. Normally, they should be aligning within different inputs: if one is higher on sample A than sample B, the other one should also be higher.
Possible solution: Use the extended version of F-Score calculation, and calculate the IoU as in:
