cupyx.scipy.ndimage.spline_filter1d#
- cupyx.scipy.ndimage.spline_filter1d(input, order=3, axis=-1, output=<class 'numpy.float64'>, mode='mirror')[source]#
Calculate a 1-D spline filter along the given axis.
The lines of the array along the given axis are filtered by a spline filter. The order of the spline must be >= 2 and <= 5.
- Parameters:
input (cupy.ndarray) – The input array.
order (int) – The order of the spline interpolation, default is 3. Must be in the range 0-5.
axis (int) – The axis along which the spline filter is applied. Default is the last axis.
output (cupy.ndarray or dtype, optional) – The array in which to place the output, or the dtype of the returned array. Default is
numpy.float64
.mode (str) – Points outside the boundaries of the input are filled according to the given mode (
'constant'
,'nearest'
,'mirror'
,'reflect'
,'wrap'
,'grid-mirror'
,'grid-wrap'
,'grid-constant'
or'opencv'
).
- Returns:
The result of prefiltering the input.
- Return type:
