spline_filter(input, order=3, output=<type 'numpy.float64'>)[source]¶
Multi-dimensional spline filter.
For more details, see
The multi-dimensional filter is implemented as a sequence of one-dimensional 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.
