WitrynaOriented object detection has been extensively inves- tigated recently in text region detection [17, 30], remote sensing [46, 28] and autonomous driving [35]. Commonly used techniques include deformable convolutional neural networks [8, 51] and spatial transformers [16]. WitrynaIntersection 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.
