DESCRIPTION

       Usage:     SmoothImage     ImageDimension     image.ext     smoothingsigma    outimage.ext
       {sigma-is-in-spacing-coordinates-0/1}  {medianfilter-0/1}   {GaussianSetMaximumError=0.01}
       {GaussianSetMaximumKernelWidth=32}

              if  median,  then sigma means radius of filtering A separate sigma can be specified
              for each dimension, e.g., 1.5x1x2
