Detailed Description

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
class itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >

Returns the weights over the support region used for B-spline interpolation/reconstruction.

Computes/evaluate the B-spline interpolation weights over the support region of the B-spline.

This class is templated over the coordinate representation type, the space dimension and the spline order.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::BSplineInterpolationWeightFunction ( ) [protected]

Get number of weights.

Member Function Documentation

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual::itk::LightObject::Pointer itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::CreateAnother ( void  ) const [virtual]

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.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual WeightsType itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::Evaluate ( const ContinuousIndexType &  index) const [virtual]

Evaluate the weights at specified ContinousIndex position. Subclasses must provide this method.

Implements itk::FunctionBase< ContinuousIndex< TCoordRep, VSpaceDimension >, Array< double > >.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual void itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::Evaluate ( const ContinuousIndexType &  index,
WeightsType &  weights,
IndexType &  startIndex 
) const [virtual]

Evaluate the weights at specified ContinousIndex position. The weights are returned in the user specified container. This function assume that weights can hold (SplineOrder + 1)^(SpaceDimension) elements. For efficiency, no size checking is done. On return, startIndex contains the start index of the support region over which the weights are defined.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual const char* itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::FunctionBase< ContinuousIndex< TCoordRep, VSpaceDimension >, Array< double > >.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual unsigned long itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::GetNumberOfWeights ( ) const [virtual]

Get number of weights.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
virtual SizeType itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::GetSupportSize ( ) const [virtual]

Get support region size.

template<class TCoordRep = float, unsigned int VSpaceDimension = 2, unsigned int VSplineOrder = 3>
static Pointer itk::BSplineInterpolationWeightFunction< TCoordRep, VSpaceDimension, VSplineOrder >::New ( ) [static]

New macro for creation of through the object factory.
