Detailed Description

template<class TScalarType = double, unsigned int NDimensions = 3, unsigned int VSplineOrder = 3>
class itk::BSplineTransform< TScalarType, NDimensions, VSplineOrder >

Deformable transform using a BSpline representation.

This class encapsulates a deformable transform of points from one N-dimensional one space to another N-dimensional space. The deformation field is modelled 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 polynomical 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 concatentated 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: 

* typedef BSplineTransform<double,2,3> TransformType;
* TransformType::Pointer 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.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

virtual void itk::BSplineTransform< TScalarType, NDimensions, VSplineOrder >::SetCoefficientImages ( const CoefficientImageArray &  images)
virtual

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.

template<class TScalarType = double, unsigned int NDimensions = 3, unsigned int VSplineOrder = 3>
virtual void itk::BSplineTransform< TScalarType, NDimensions, VSplineOrder >::SetFixedParameters ( const ParametersType &  parameters)
virtual

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.

virtual

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.
