Detailed Description

This filter uses a convolution with Spline basis functions.

It can be used to interpolate a signal from its spline representation

Function-like operator that filters a given volume

Write result in an existing volume. If the allocated size differs from the needed resulting size, the volume is reallocated.

DirectBSplineFilter overrides the inherited version to add normalization.

Note: 1 copy

Warning: This call risks causing additional precision errors
