spline_filter1d(input, order=3, axis=-1, output=<class 'numpy.float64'>)¶
Calculate 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.
- 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
- spline_filter1d : ndarray
The filtered input.
