WebIntersection over union (IoU) of boxes is widely used as an evaluation metric in object detection ( 1, 2 ). In 2D, IoU is commonly applied to axis-aligned boxes, namely boxes with edges parallel to the image axis. In 3D, boxes are usually not axis aligned and can be oriented in any way in the world. We introduce a new algorithm which computes ... WebThe symbol ∪ is employed to denote the union of two sets. Thus, the set A ∪ B—read “A union B” or “the union of A and B”—is defined as the set that consists of all elements belonging to either set A or set B (or both).
