Detailed Description

template<class TInputImage, class TCoordRep = double>
class itk::InterpolateImageFunction< TInputImage, TCoordRep >

Base class for all image interpolaters.

InterpolateImageFunction is the base for all ImageFunctions that interpolates image intensity at a non-integer pixel position. This class is templated over the input image type and the coordinate representation type (e.g. float or double ).

Warning:: This heirarchy of functions work only for images with scalar pixel types. For images of vector pixel types use VectorInterpolateImageFunctions.
