#include <itkBSplineTransform.h>

Detailed Description

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

Deformable transform using a BSpline representation.

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 transform domain (origin, physical dimensions, direction) and B-spline mesh size where the mesh size is the number of polynomial patches comprising the finite domain of support. The relationship between the mesh size ( number of polynomial pieces) and the number of control points in any given dimension is

mesh size = number of control points - spline order

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.

The parameters for this transform is 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 to form a single array.

The following illustrates the typical usage of this class:

using TransformType = BSplineTransform<double,2,3>;
auto transform = TransformType::New();
transform->SetTransformDomainOrigin( origin );
transform->SetTransformDomainPhysicalDimensions( physicalDimensions );
transform->SetTransformDomainDirection( direction );
transform->SetTransformDomainMeshSize( meshSize );
// 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 fixed parameters of the transform are 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.

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

This method sets the fixed parameters of the transform. For a BSpline deformation transform, the fixed parameters are the following: grid size, grid origin, grid spacing, and grid direction. However, all of these are set via the much more intuitive SetTransformDomainXXX() functions

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

With recent updates to this transform, however, all these parameters are set indirectly by setting the transform domain parameters unless the user sets them with SetFixedParameters().

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

Transform points by a BSpline deformable transformation. On return, weights contains the interpolation weights used to compute the deformation and indices of the x (zeroth) dimension coefficient parameters in the support region used to compute the deformation. Parameter indices for the i-th dimension can be obtained by adding ( i * this->GetNumberOfParametersPerDimension() ) to the indices array.

Implements itk::BSplineBaseTransform< TParametersValueType, VDimension, VSplineOrder >.
