* \brief This filter is here for backwards compatibility. It has been renamed to
* VectorMagnitudeImageFilter in the ImageIntensity module.
*
* Take an image of vectors as input and produce an image with the
* magnitude of those vectors.
*
* The filter expects the input image pixel type to be a vector and
* the output image pixel type to be a scalar.
*
* This filter assumes that the PixelType of the input image is a VectorType
* that provides a GetNorm() method.
