top = max(top_box, coord_h-1) down = min(down_box, coord_h+1) left = max(coord_w-1, left_box) right = min(right_box, coord_w+1)

why don't directly set "top" to "coord_h-1", "down" to "coord_h+1"? There are still few positive samples.

@Hanawh Here we aim at limiting the positives samples collected in the sampling region. The way you mentioned directly sets the number of positives to 9, which should also work.
