scipy.ndimage.morphology.morphological_laplace(input, size=None, footprint=None, structure=None, output=None, mode='reflect', cval=0.0, origin=0)

Multi-dimensional morphological laplace.

Parameters :

input : array_like

Input.

size : int or sequence of ints, optional

See structure.

footprint : bool or ndarray, optional

See structure.

structure : structure

Either size, footprint, or the structure must be provided.

output : ndarray

An output array can optionally be provided.

mode : {‘reflect’,’constant’,’nearest’,’mirror’, ‘wrap’}, optional

The mode parameter determines how the array borders are handled. For ‘constant’ mode, values beyond borders are set to be cval. Default is ‘reflect’.

cval : scalar, optional

Value to fill past edges of input if mode is ‘constant’. Default is 0.0

origin : origin

The origin parameter controls the placement of the filter.

Returns :

morphological_laplace : ndarray

Output
