* \brief Wrap an ImageToImageFilter as a VideoToVideoFilter that operates on
* a single frame at a time
*
* This filter wrapper allows all of the standard ITK image filters to be used
* in a video pipeline. This is done by instantiating the image filter, setting
* its parameters, and then using the SetImageFilter() method of this wrapper
* to use the filter to process each in a video pipeline. An instance of this
* wrapper must be templated over the appropriate image filter type.
