ContinuousIndex< TCoordRep, VSpaceDimension > ContinuousIndexType
BSpline kernel used for density estimation and nonparameteric regression.
Array2D class representing a 2D array with size defined at construction time.
Definition: itkArray2D.h:45
Base class for all ITK function objects.
virtual WeightsType Evaluate(const ContinuousIndexType &index) const override
A templated class holding a point in n-Dimensional image space.
Control indentation during Print() invocation.
Definition: itkIndent.h:49
FunctionBase< ContinuousIndex< TCoordRep, VSpaceDimension >, Array< double > > Superclass
Returns the weights over the support region used for B-spline interpolation/reconstruction.
Represent a n-dimensional index in a n-dimensional image.
Definition: itkIndex.h:71
void PrintSelf(std::ostream &os, Indent indent) const override
