Why sort bbox with objectness score (Pobj) rather than individual class score (Pc)
util.py line 149
conf_sort_index = torch.sort(image_pred_class[:,4], descending = True )[1]
I searched NMS sort bbox with Pc and compute the rest bbox IoU with Top Pc score bbox then throw away bboxes IoU bigger than treshhold.
And this code is Pobj...
