For better optimization and better performance , use anchor encode bbox in the second stage like as the first stage instead of rois. But something needs to be noted here.
- Is the anchor the same as that in the first stage ?( anchor consistence)
- If not , how to do it ?( find the best anchor that has max iou with rois and their according gt box)
