class morphological_gradient_external[source]#

Bases:

Compute the external morphological gradient of an array.

Parameters:

  • array (NDArray) – The input array to compute the external morphological gradient of.

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

  • structure (Union[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.

Returns:

The external morphological gradient of the input array.

Return type:

NDArray
