Detailed Description

template<class TInputImage, class TOutput, class TCoordRep = float>
class itk::ImageFunction< TInputImage, TOutput, TCoordRep >

Evaluates a function of an image at specified position.

ImageFunction is a baseclass for all objects that evaluates a function of an image at index, continuous index or point. This class is templated over the input image type, the type of the function output and the coordinate representation type (e.g. float or double).

The input image is set via method SetInputImage(). Methods Evaluate, EvaluateAtIndex and EvaluateAtContinuousIndex respectively evaluates the function at an geometric point, image index and continuous image index.

Warning:
Image BufferedRegion information is cached during in SetInputImage( image ). If the image BufferedRegion has changed one must call SetInputImage( image ) again to update the cache to the current values.
