cupyx.scipy.ndimage.morphological_laplace(input, size=None, footprint=None, structure=None, output=None, mode='reflect', cval=0.0, origin=0, *, axes=None)[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.
axes (tuple of int or None) – The axes over which to apply the filter. If None, input is filtered along all axes. If an origin tuple is provided, its length must match the number of axes.

Returns:

The morphological laplace of the input.

Return type:

cupy.ndarray
