- cupyx.scipy.ndimage.laplace(input, output=None, mode='reflect', cval=0.0)#
Multi-dimensional Laplace filter based on approximate second derivatives.
input (cupy.ndarray) – The input array.
output (cupy.ndarray, dtype or None) – The array in which to place the output. Default is is same dtype as the input.
mode (str) – The array borders are handled according to the given mode (
'wrap'). Default is
cval (scalar) – Value to fill past edges of input if mode is
'constant'. Default is
The result of the filtering.
- Return type:
When the output data type is integral (or when no output is provided and input is integral) the results may not perfectly match the results from SciPy due to floating-point rounding of intermediate results.
