I am studying Detectron2 implementation of Mask-RCNN. I am trying to understand why there is a max( , 0.1) needed in masks.rasterize_polygons_within_box
# 2. Rescale the polygons to the new box size ratio_h = mask_size / max(h, 0.1) ratio_w = mask_size / max(w, 0.1)
Here, h and w are the height and width of the box. Where does the number 0.1 come from? Is that just to prevent a divide by zero error?
