spline_filter(input, order=3, output=<class 'numpy.float64'>, mode='mirror')¶
Multidimensional spline filter.
For more details, see
The multidimensional filter is implemented as a sequence of 1-D spline filters. The intermediate arrays are stored in the same data type as the output. Therefore, for output types with a limited precision, the results may be imprecise because intermediate results may be stored with insufficient precision.
