bounding_box_size = (det[:, 2] - det[:, 0]) * (det[:, 3] - det[:, 1])
img_center = img_size / 2

det = det[index, :]

bb = np.zeros(4, dtype=np.int32)
#print(det[0], det[1], det[2], det[3])
bb[0] = np.maximum(det[0] - args.margin / 2, 0) # ??????
bb[1] = np.maximum(det[1] - args.margin / 2, 0) # ????
bb[2] = np.minimum(det[2] + args.margin / 2, img_size[1])
bb[3] = np.minimum(det[3] + args.margin / 2, img_size[0])
index = np.argmax(bounding_box_size - offset_dist_squared * 2.0) what means?
答案 0 :(得分：0)
用边框填充边框吗？
