Detailed Description

template<typename TParametersValueType = double, unsigned int VDimension = 3, unsigned int VSplineOrder = 3>
class itk::BSplineDeformableTransform< TParametersValueType, VDimension, VSplineOrder >

Deformable transform using a BSpline representation.

Note: BSplineTransform is a newer version of this class, and it is preferred.

This class encapsulates a deformable transform of points from one N-dimensional space to another N-dimensional space. The deformation field is modeled using B-splines. A deformation is defined on a sparse regular grid of control points \( \vec{\lambda}_j \) and is varied by defining a deformation \( \vec{g}(\vec{\lambda}_j) \) of each control point. The deformation \( D(\vec{x}) \) at any point \( \vec{x} \) is obtained by using a B-spline interpolation kernel.

The deformation field grid is defined by a user specified GridRegion, GridSpacing and GridOrigin. Each grid/control point has associated with it N deformation coefficients \( \vec{\delta}_j \), representing the N directional components of the deformation. Deformation outside the grid plus support region for the BSpline interpolation is assumed to be zero.

Additionally, the user can specified an addition bulk transform \( B \) such that the transformed point is given by:

\[ \vec{y} = B(\vec{x}) + D(\vec{x}) \]

The parameters for this transform is an N x N-D grid of spline coefficients. The user specifies the parameters as one flat array: each N-D grid is represented by an array in the same way an N-D image is represented in the buffer; the N arrays are then concatenated together on form a single array.

For efficiency, this transform does not make a copy of the parameters. It only keeps a pointer to the input parameters and assumes that the memory is managed by the caller.

The following illustrates the typical usage of this class:

using TransformType = BSplineDeformableTransform<double,2,3>;
TransformType::Pointer transform = TransformType::New();
 
transform->SetGridRegion( region );
transform->SetGridSpacing( spacing );
transform->SetGridOrigin( origin );
 
// NB: the region must be set first before setting the parameters
 
TransformType::ParametersType parameters( transform->GetNumberOfParameters() );
 
// Fill the parameters with values
 
transform->SetParameters( parameters )
 
outputPoint = transform->TransformPoint( inputPoint );

An alternative way to set the B-spline coefficients is via array of images. The grid region, spacing and origin information is taken directly from the first image. It is assumed that the subsequent images are the same buffered region. The following illustrates the API:

TransformType::ImageConstPointer images[2];
 
// Fill the images up with values
 
transform->SetCoefficientImages( images );
outputPoint = transform->TransformPoint( inputPoint );

Warning: use either the SetParameters() or SetCoefficientImages() API. Mixing the two modes may results in unexpected results.

The class is templated coordinate representation type (float or double), the space dimension and the spline order.

◆ SetCoefficientImageInformationFromFixedParameters()

template<typename TParametersValueType = double, unsigned int VDimension = 3, unsigned int VSplineOrder = 3>

void itk::BSplineDeformableTransform< TParametersValueType, VDimension, VSplineOrder >::SetCoefficientImageInformationFromFixedParameters ( )

overrideprivatevirtual

Construct control point grid size from transform domain information

Implements itk::BSplineBaseTransform< double, 3, 3 >.

◆ SetCoefficientImages()

template<typename TParametersValueType = double, unsigned int VDimension = 3, unsigned int VSplineOrder = 3>

void itk::BSplineDeformableTransform< TParametersValueType, VDimension, VSplineOrder >::SetCoefficientImages ( const CoefficientImageArray & images )

overridevirtual

Set the array of coefficient images.

This is an alternative API for setting the BSpline coefficients as an array of SpaceDimension images. The fixed parameters are taken from the first image. It is assumed that the buffered region of all the subsequent images are the same as the first image. Note that no error checking is done.

Warning: use either the SetParameters() or SetCoefficientImages() API. Mixing the two modes may results in unexpected results.

Implements itk::BSplineBaseTransform< double, 3, 3 >.

◆ SetFixedParameters()

template<typename TParametersValueType = double, unsigned int VDimension = 3, unsigned int VSplineOrder = 3>

void itk::BSplineDeformableTransform< TParametersValueType, VDimension, VSplineOrder >::SetFixedParameters ( const FixedParametersType & passedParameters )

overridevirtual

This method sets the fixed parameters of the transform. For a BSpline deformation transform, the parameters are the following: Grid Size, Grid Origin, and Grid Spacing

The fixed parameters are the three times the size of the templated dimensions. This function has the effect of make the following calls: transform->SetGridSpacing( spacing ); transform->SetGridOrigin( origin ); transform->SetGridDirection( direction ); transform->SetGridRegion( bsplineRegion );

This function was added to allow the transform to work with the itkTransformReader/Writer I/O filters.

private

The variables defining the coefficient grid domain for the InternalParametersBuffer are taken from the m_CoefficientImages[0] image, and must be kept in sync with them. by using references to that instance, this is more naturally enforced and does not introduce a speed penalty of dereferencing through the pointers (although it does enforce some internal class synchronization).
