cupyx.scipy.ndimage.morphological_laplace(input, size=None, footprint=None, structure=None, output=None, mode='reflect', cval=0.0, origin=0)[source]#

Multidimensional morphological laplace.

Parameters:

input (cupy.ndarray) – The input array.
size (tuple of ints) – Shape of a flat and full structuring element used for the morphological laplace. Optional if footprint or structure is provided.
footprint (array of ints) – Positions of non-infinite elements of a flat structuring element used for morphological laplace. Non-zero values give the set of neighbors of the center over which opening is chosen.
structure (array of ints) – Structuring element used for the morphological laplace. structure may be a non-flat structuring element.
output (cupy.ndarray, dtype or None) – The array in which to place the output.
mode (str) – The array borders are handled according to the given mode ('reflect', 'constant', 'nearest', 'mirror', 'wrap'). Default is 'reflect'.
cval (scalar) – Value to fill past edges of input if mode is constant. Default is 0.0.
origin (scalar or tuple of scalar) – The origin parameter controls the placement of the filter, relative to the center of the current element of the input. Default of 0 is equivalent to (0,)*input.ndim.

Returns:

The morphological laplace of the input.

Return type:

cupy.ndarray
