void itk::fem::RobustSolver< VDimension >::RescaleLandmarkStiffnessMatrix ( double  oldPointTensorPonderation)
protected

Adjust the landmark stiffness matrix based on the change of the number of the landmarks. The argument depend on the number of landmarks and the number of node in the mesh. This method update the value of the ponderation based on a previous ponderation value and the computed Landmark Tensor ponderation returned by the GetLandmarkTensorPonderation() method.

virtual void itk::fem::RobustSolver< VDimension >::SetFractionErrorRejected ( double  _arg)
virtual

This variable control the fraction of landmarks that will be rejected as outliers. It is expected to be a number between 0.0 and 1.0.

template<unsigned int VDimension = 3>
virtual void itk::fem::RobustSolver< VDimension >::SetOutlierRejectionSteps ( unsigned int  _arg)
virtual

Number of iterations to be run in which outliers will be removed.

template<unsigned int VDimension = 3>
virtual void itk::fem::RobustSolver< VDimension >::SetToleranceToLargestDisplacement ( double  _arg)
virtual

This variable set the largest error that will be tolerated when rejecting outliers. It is expected to be a value from 0.0 to 1.0, and represents a fraction of the largest error in the collection of feature points.

template<unsigned int VDimension = 3>
virtual void itk::fem::RobustSolver< VDimension >::SetTradeOffImageMeshEnergy ( double  _arg)
virtual

Control the balance between the Mesh deformation energy and the matching energy. The range of values is from 0.0 to 1.0. When set to zero, the matching energy is not considered. When set to 1.0 the solver with consider equally the Mesh energy and the matching energy.

template<unsigned int VDimension = 3>
void itk::fem::RobustSolver< VDimension >::UnselectLandmarks ( unsigned int  numberOfRejectedBlocksPerStep)
protected

Unselect landmark from landmark array. The argument defines how many landmarks will be unselected, after they have already been sorted. This method must be called after NthElementWRTDisplacementError() has been invoked to sort the landmarks.
