and object size. We directly prove this by visualizing
the offset field in the feature map viewpoint and the
kernel viewpoint separately. The position of the ob-
ject is global information which is in the feature map
viewpoint while the size of the object is local infor-
mation which is in the kernel viewpoint. The effect of
the offset field in the two viewpoints is investigated
separately and the results show the components in the
kernel viewpoint improves the deformable convolu-
tion more.
