Detailed Description

template<class TInputImage, class TOutputImage, class TCoordType = typename TInputImage::PixelType, class InterpolatorType = BSplineInterpolateImageFunction<TInputImage, TCoordType>>
class itk::InterpolateImagePointsFilter< TInputImage, TOutputImage, TCoordType, InterpolatorType >

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 seperate images for each dimension. The coordinates are treated as Continuous Indicies. If coordinates are supplied as Points then they must be converted to an Index before passing to this class.
