cupyx.scipy.ndimage.correlate#
- cupyx.scipy.ndimage.correlate(input, weights, output=None, mode='reflect', cval=0.0, origin=0)[source]#
Multi-dimensional correlate.
The array is correlated with the given kernel.
- Parameters:
input (cupy.ndarray) – The input array.
weights (cupy.ndarray) – Array of weights, same number of dimensions as input
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 is0.0
.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 result of correlate.
- Return type:

Note
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.
