[Insight-users] Finding the median of the neighborhood of a p ixel

[Miller, James V (Research)]

We would have to add a method to the MedianImageFunction to set the
radii of the neighborhood used for the calculation.  

Lines 74-75 of itkMedianImageFunction.txx hard wire a 3x3x3x.... neighorhood.

So we just need a Set/Get method in the header to set the kernel size and then
use use that size in line 78 and remove lines 74-75

Thanks for the response, James!

I thought about doing this, but how do I specify the neighborhood I
want to use?  In this particular case, how do I calculate the median
of a 3x3 or 5x5 neighborhood of the pixel at (13,200)?  To me, the
above code looks as if it uses the largest possible neighborhood
regardless.
