spline_filter1d
(input, order=3, axis=-1, output=<type 'numpy.float64'>)[source]¶ Calculates a one-dimensional 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 : array_like
The input array.
order : int, optional
The order of the spline, default is 3.
axis : int, optional
The axis along which the spline filter is applied. Default is the last axis.
output : ndarray or dtype, optional
The array in which to place the output, or the dtype of the returned array. Default is
numpy.float64
.Returns: spline_filter1d : ndarray or None
The filtered input. If output is given as a parameter, None is returned.
