Detailed Description

template<typename TTransform>
class itk::BSplineTransformParametersAdaptor< TTransform >

BSplineTransformParametersAdaptor adapts a BSplineTransform to the new specified fixed parameters.

The fixed parameters of the BSplineTransform store the following information (in order as they appear in m_FixedParameters): grid size grid origin grid spacing grid direction

During multiresolution image registration it is often desired to also increase the B-spline grid resolution for greater flexibility in optimizing the transform. As defined in the base class, the user can change the resolution via

transformAdaptor->SetTransform( transform );
transformAdaptor->SetRequiredFixedParameters( fixedParameters );
transformAdaptor->AdaptTransformParameters();

or the user can use the more intuitive API for setting the fixed parameters. E.g., often the user will want to maintain the same transform domain spatial extent but only increase the mesh size. This can be done as follows:

transformAdaptor->SetTransform( transform );
transformAdaptor->SetRequiredTransformDomainOrigin( transform->GetTransformDomainOrigin() );
transformAdaptor->SetRequiredTransformDomainDirection( transform->GetTransformDomainDirection() );
transformAdaptor->SetRequiredTransformDomainPhysicalDimensions( transform->GetTransformDomainPhysicalDimensions() );
transformAdaptor->SetRequiredTransformDomainMeshSize( newMeshSize );
transformAdaptor->AdaptTransformParameters();
