Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction< TInputImage, TCoordRep >

Linearly interpolate or NN extrapolate a vector image at specified positions.

VectorLinearInterpolateNearestNeighborExtrapolateImageFunction linearly interpolates (or NN extrapolates) a vector image intensity non-integer pixel position. This class is templated over the input image type and the coordinate representation type.

This class is designed to work as a VectorInterpolateImageFunction, hence the IsInsideBuffer(PointType p) is overridden to always answer true

This function works for N-dimensional images.

Author:

Tom Vercauteren, INRIA & Mauna Kea Technologies

Warning:

This function work only for Vector images. For scalar images use LinearInterpolateImageFunction.
