elastix::BSplineInterpolator< TElastix > Class Template Reference

#include <elxBSplineInterpolator.h>

Detailed Description

template<class TElastix>
class elastix::BSplineInterpolator< TElastix >

An interpolator based on the itkBSplineInterpolateImageFunction.

This interpolator interpolates images with an underlying B-spline polynomial.

NB: BSplineInterpolation with order 1 is slower than using a LinearInterpolator, but it determines the derivative slightly more accurate at grid points. That's why the registration results can be slightly different.

The parameters used in this class are:

Parameters

Interpolator: Select this interpolator as follows:
(Interpolator "BSplineInterpolator")

BSplineInterpolationOrder: the order of the B-spline polynomial.
example: (BSplineInterpolationOrder 3 2 3)
The default order is 1. The parameter can be specified for each resolution.
If only given for one resolution, that value is used for the other resolutions as well.
