that's a simple one - your image did not load (and thus is empty / None).
lesson here, whenever you read any resource from disc, you have to check if that operation succeeded !
img = cv2.imread('result.jpg')
if img not None:
## do something with img
even if you use exactly the same code, as other people, your filestructure might differ, so, again: CHECK !
