#include <itkBSplineExponentialDiffeomorphicTransform.h>

Detailed Description

template<typename TParametersValueType, unsigned int VDimension>
class itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >

Exponential transform using B-splines as the smoothing kernel.

Exponential transform inspired by the work of J. Ashburner (see reference below). Assuming a constant velocity field, the transform takes as input the update field at time point t = 1, \(u\) and smooths it using a B-spline smoothing (i.e. fitting) operation, \(S_{update}\) defined by SplineOrder and NumberOfControlPointsForTheUpdateField. We add that the current estimate of the velocity field and then perform a second smoothing step such that the new velocity field is

\begin{eqnarray*} v_{new} = S_{velocity}( v_{old} + S_{update}( u ) ). \end{eqnarray*}

We then exponentiate \(v_{new}\) using the class ExponentialDisplacementImageFilter to yield both the forward and inverse displacement fields.

See [4] for more details.

template<typename TParametersValueType, unsigned int VDimension>

virtual SplineOrderType itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::GetSplineOrder ( ) const

virtual

Set/Get the spline order.

◆ New()

template<typename TParametersValueType, unsigned int VDimension>

static Pointer itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::New ( )

static

New macro for creation of through a Smart Pointer

◆ PrintSelf()

template<typename TParametersValueType, unsigned int VDimension>

void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::PrintSelf	(	std::ostream &	os,
		Indent	indent ) const

overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::LightObject.

◆ SetMeshSizeForTheConstantVelocityField()

template<typename TParametersValueType, unsigned int VDimension>

void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::SetMeshSizeForTheConstantVelocityField ( const ArrayType & )

Set the update field mesh size which is used to specify the control point grid size. The mesh size in each dimension is calculated as the difference between the control point grid size and the spline order, i.e. meshSize = controlPointGridSize - SplineOrder.

◆ SetMeshSizeForTheUpdateField()

template<typename TParametersValueType, unsigned int VDimension>

void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::SetMeshSizeForTheUpdateField ( const ArrayType & )

Set the velocity field mesh size which is used to specify the control point grid size. The mesh size in each dimension is calculated as the difference between the control point grid size and the spline order, i.e. meshSize = controlPointGridSize - SplineOrder.

◆ SetNumberOfControlPointsForTheConstantVelocityField()

template<typename TParametersValueType, unsigned int VDimension>

virtual void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::SetNumberOfControlPointsForTheConstantVelocityField ( ArrayType _arg )

virtual

Set/Get the control point grid size defining the B-spline estimate of the smoothed velocity field. In each dimension, the B-spline mesh size is equal to the number of control points in that dimension minus the spline order. Default = 4 control points in each dimension for a mesh size of 1 in each dimension.

◆ SetNumberOfControlPointsForTheUpdateField()

template<typename TParametersValueType, unsigned int VDimension>

virtual void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::SetNumberOfControlPointsForTheUpdateField ( ArrayType _arg )

virtual

Set the control point grid size defining the B-spline estimate of the smoothed update field. In each dimension, the B-spline mesh size is equal to the number of control points in that dimension minus the spline order. Default = 4 control points in each dimension for a mesh size of 1 in each dimension.

◆ SetSplineOrder()

template<typename TParametersValueType, unsigned int VDimension>

virtual void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::SetSplineOrder ( SplineOrderType _arg )

virtual

Set/Get the spline order.

◆ UpdateTransformParameters()

template<typename TParametersValueType, unsigned int VDimension>

void itk::BSplineExponentialDiffeomorphicTransform< TParametersValueType, VDimension >::UpdateTransformParameters	(	const DerivativeType &	update,
		ScalarType	factor = 1.0 )

overridevirtual

Update the transform's parameters by the values in update. We overwrite the base class implementation as we might want to smooth the update field before adding it to the velocity field

Reimplemented from itk::Transform< TParametersValueType, VDimension, VDimension >.
