box_area and box_iou functions for cxcywh format #8961
Description
🚀 The feature
Native box_area and box_iou functions for cxcywh format.
Motivation, pitch
Since the cxcywh format is common, we can use faster and simpler functions to calculate box area and box IoU directly in this format.
Currently, we first need to convert to the xyxy format before using box_area and box_iou in torchvision.
