  • size (Union[Union[int, Tuple[int, int]], None] = None) – The size of the structuring element. If None, structure must be provided.

  • structure (Union[np.ndarray, None] = None) – The structuring element. If None, size must be provided.

  • mode (PaddingType = "reflect") – The padding mode to use.

  • maxval (float = 1e4) – Value to assume for infinite elements in the kernel.
