elastix::DisplacementMagnitudePenalty< TElastix > Class Template Reference

#include <elxDisplacementMagnitudePenalty.h>

Detailed Description

template<class TElastix>
class elastix::DisplacementMagnitudePenalty< TElastix >

A penalty term that penalises ||T(x)-x||.

This penalty term may look a little unusual, but it can be used as a way to compute an inverse transform, by supplying the transform to be inverted as an initial transform and setting the HowToCombineTransforms parameter to "Compose".

The parameters used in this class are:

Parameters:

Metric: Select this metric as follows:
(Metric "DisplacementMagnitudePenalty")
