FEMRobustSolver Class Reference

#include <itkFEMRobustSolver.h>

Detailed Description

A FEM solver characterized by accommodating outliers or noises in landmarks and advancing approximation to interpolation. This solver takes a FEMObject as input and outputs a deformed FEMObject.

*       typedef itk::fem::FEMObject<3>    FEMObjectType;
*       FEMObjectObjectType::Pointer fem = FEMObjectObjectType::New();
*       ...
*       typedef itk::fem::RobustSolver<3>    FEMSolverType;
*       FEMSolverType::Pointer solver = FEMSolverType::New();
*
*       solver->SetInput( fem );
*       solver->Update( );
*       FEMSolverType::Pointer defem = solver->GetOutput( );
*   ...
* 

For the purpose of easy-of-use, a FEMScatteredDataPointSetToImageFilter is developed to facilitate the use of this solver by hiding the details about the FEMObject. FEMScatteredDataPointSetToImageFilter takes a mesh and a feature point set as inputs and converts them into a FEMObject, then calls this solver to find the solution. Based on the solution and the user specified grid, a deformation field is generated.
