split_path = f.rsplit(".") only can't handle filenames that contain more than "." Ex: file.30.26.jpg
It will produce an opencv write error. (It will try to cv.imwrite("file.30",img ).
In this modification, I join all elements of split_path array from the start to (n - 1) th to create new split_path with just 2 elements.
Ex: file.30.26.jpg -> ["file","30","26","jpg"] -> ["file.30.26","jpg"]
