#include <itkInterpolateImagePointsFilter.h>
Resamples an image at the coordinates specified by the user.
This class may be templated over the Interpolate Function but defaults to the BSplineInterpolateImageFunction for cubic interpolation. The user must set the image using the SetInputImage function and they must set the coordinates (one coordinate "image" for each dimension) using SetInterpolationCoordinate(). The coordinates may be any number of points and can be randomly organized. The interpolated output will correspond to the ordering of the coordinate points. The coordinates must be of type ContinuousIndexType and not of PointType.
This function is different from the resampleImageFilter class in that the resampleImageFilter applies a transform to the original input image coordinates. This function takes an arbitrary set of point coordinates and applies the transform at these locations.
Limitations: The coordinates must be in an image of the same dimension as the input image. There is no reason why this should be the case and future revisions should look at eliminating this limitation. Currently TCoordType must be the same as the input pixel type (TInputImage). Again future revisions should look at eliminating this limitation. Though the output generation may be streamed the entire input image, must be supplied. The coordinates may be streamed in smaller blocks. The coordinates are specified as separate images for each dimension. The coordinates are treated as Continuous Indices. If coordinates are supplied as Points then they must be converted to an Index before passing to this class.

If an imaging filter needs to perform processing after the buffer has been allocated but before threads are spawned, the filter can can provide an implementation for BeforeThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

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.

Set the pixel value when a transformed pixel is outside of the image
void itk::InterpolateImagePointsFilter< TInputImage, TOutputImage, TCoordType, InterpolatorType >::SetInputImage | ( | const TInputImage * | inputImage | ) |
SetInputImage is used to set the image to be interpolated. Note that this should be used instead of the direct setInput as multiple inputs are needed and this class keeps track of the ordering.
void itk::InterpolateImagePointsFilter< TInputImage, TOutputImage, TCoordType, InterpolatorType >::SetInterpolationCoordinate | ( | const CoordImageType * | coordinate, |
unsigned int | setDimension | ||
) |
SetInterpolationCoordinate must be called for each dimension. The variable setDimension is used to identify the dimension being set, i.e. 0,1,2...N

Main function for calculating interpolated values at each coordinate set. Access is through the update() call. TODO: This needs to be modified for a threaded implementation.
