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.
