/**
* @class vtkImageHybridMedian2D
* @brief Median filter that preserves lines and
* corners.
*
* vtkImageHybridMedian2D is a median filter that preserves thin lines and
* corners. It operates on a 5x5 pixel neighborhood. It computes two values
* initially: the median of the + neighbors and the median of the x
* neighbors. It then computes the median of these two values plus the center
* pixel. This result of this second median is the output pixel value.
