Detailed Description

template<typename TInputPointSet, typename TOutputImage>
class itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >

Image filter which provides a B-spline output approximation.

Given an n-D image with scattered data, this filter finds a fast approximation to that irregularly spaced data using uniform B-splines. The traditional method of inverting the observation matrix to find a least-squares fit is made obsolete. Therefore, memory issues are not a concern and inverting large matrices is not applicable. In addition, this allows fitting to be multi-threaded. This class generalizes from Lee's original paper to encompass n-D data in m-D parametric space and any feasible B-spline order as well as the option of specifying a confidence value for each point.

In addition to specifying the input point set, one must specify the number of control points. The specified number of control points must be greater than m_SplineOrder. If one wishes to use the multilevel component of this algorithm, one must also specify the number of levels in the hierarchy. If this is desired, the number of control points becomes the number of control points for the coarsest level. The algorithm then increases the number of control points at each level so that the B-spline n-D grid is refined to twice the previous level.

There are two parts to fitting scattered data: the parameterization assignment problem and the fitting problem given a parameterization. This filter only addresses the second problem in that the user must provide a parametric value for each scattered datum. Different parametric assignment schemes result in different B-spline object outputs.

This filter is general in that it accepts n-D scattered data in m-D parametric dimensions. Input to this filter is an m-D point set with a Vector data type of n dimensions. This means that the parametric values are stored in the points container of the point set whereas the scattered data are stored in the points data container of the point set.

Typical B-spline objects include curves, which have a parametric dimension of 1 and a data dimension of 2 or 3 (depending on the space in which the curve resides) and deformation fields which commonly have parametric and data dimensions of 2 or 3 (again depending on the space of the field). As an example, a curve through a set of 2D points has data dimension 2 and parametric dimension 1. The univariate curve could be represented as: <x(u),y(u)> Another example is a 3D deformation of 3D points, which has parametric dimension 3 and data dimension 3 and can be represented as: <dx(u,v,w), dy(u,v,w), dz(u,v,w)>. However, as mentioned before, the code is general such that, if the user wanted, she could model a time varying 3-D displacement field which resides in 4-D space as <dx(u, v, w, t), dy(u, v, w, t), dz(u, v, w, t)>.

The output is an image defining the sampled B-spline parametric domain where each pixel houses the sampled B-spline object value. For a curve fit to 3-D points, the output is a 1-D image where each voxel contains a vector with the approximated (x,y,z) location. The continuous, finite, rectilinear domain (as well as the sampling rate) is specified via the combination of the SetSpacing() and SetSize() functions. For a 2-D deformation on 2-D points, the output is a 2-D image where each voxel contains the approximated (dx, dy) vector.

The parameterization must be specified using SetPoint, where the actual coordinates of the point are set via SetPointData. For example, to compute a spline through the (ordered) 2D points (5,6) and (7,8), you should use:

using DataType = itk::Vector< float, 2 >;
PointSetType::PointType param0;
param0[0] = 0.0;
DataType p0;
p0[0] =  10.0; p0[1]= 10.0;
pointSet->SetPoint(0, param0);
pointSet->SetPointData( 0, p0 );
 
PointSetType::PointType param1;
param1[0] = 1.0;
DataType p1;
p1[0] =  80.0; p1[1]= 50.0;
pointSet->SetPoint(1, param1);
pointSet->SetPointData( 1, p1 );

overrideprotectedvirtual

If an imaging filter needs to perform processing after all processing threads have completed, the filter can can provide an implementation for AfterThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

◆ GenerateData()

template<typename TInputPointSet , typename TOutputImage >

void itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >::GenerateData ( )

overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.

◆ GenerateOutputImage()

template<typename TInputPointSet , typename TOutputImage >

void itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >::GenerateOutputImage ( )

private

This function is not used as it requires an evaluation of all (SplineOrder+1)^ImageDimensions B-spline weights for each evaluation.

◆ GenerateOutputImageOn()

template<typename TInputPointSet , typename TOutputImage >

virtual void itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >::GenerateOutputImageOn ( )

virtual

Set/Get whether or not the sampled output B-spline object is constructed. The result of the fitting process is an n-D grid of control points which describe the continuous B-spline object.

◆ GetBSplineEpsilon()

template<typename TInputPointSet , typename TOutputImage >

virtual RealType itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >::GetBSplineEpsilon ( ) const

virtual

Set/Get the epsilon used for B-splines. The B-spline parametric domain in 1-D is defined on the half-closed interval [a,b). Extension to n-D is defined similarly. This presents some difficulty for defining the the image domain to be co-extensive with the parametric domain. We use the B-spline epsilon to push the edge of the image boundary inside the B-spline parametric domain.

◆ GetCloseDimension()

template<typename TInputPointSet , typename TOutputImage >

virtual const ArrayType& itk::BSplineScatteredDataPointSetToImageFilter< TInputPointSet, TOutputImage >::GetCloseDimension ( ) const

virtual

Set/Get the array to define the periodicity of the dimensions in the parametric space is to be. This array of 0/1 values defines whether a particular dimension of the parametric space is to be considered periodic or not. For example, if you are using interpolating along a 1D closed curve, the array type will have size 1, and you should set the first element of this array to the value "1". In the case that you were interpolating in a planar surface with cylindrical topology, the array type will have two components, and you should set to "1" the component that goes around the cylinder, and set to "0" the component that goes from the top of the cylinder to the bottom. This will indicate the periodicity of that parameter to the filter. Internally, in order to make periodic the domain of the parameter, the filter will reuse some of the points at the beginning of the domain as if they were also located at the end of the domain. The number of points to be reused will depend on the spline order. As a user, you don't need to replicate the points, the filter will do this for you.
