itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction< TInputImage, TCoordinate > Class Template Reference

#include <itkVectorLinearInterpolateNearestNeighborExtrapolateImageFunction.h>

Detailed Description

template<typename TInputImage, typename TCoordinate = float>
class itk::VectorLinearInterpolateNearestNeighborExtrapolateImageFunction< TInputImage, TCoordinate >

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.

Warning

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

Evaluate the function at a ContinuousIndex position

Returns the linearly interpolated image intensity at a specified point position. If the point does not lie within the image buffer a nearest neighbor interpolation is done.

Implements itk::VectorInterpolateImageFunction< TInputImage, TCoordinate >.

Evaluate the function at an index position

Simply returns the image value at the specified index position. If the index does not lie within the image buffer a nearest neighbor interpolation is done.
