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

[Miller, James V (Research)]

MedianImageFunction is what you want.  Your code will look something like this...

itk::MedianImageFunction::Pointer  median = itk::MedianImageFunction::New();
median->SetInputImage(someImage);
itk::Index<2> index;
index[0] = 13;
index[1] = 200;

double medianValue;
medianValue = median->Evaluate(index);

pixel


Hi all!

Does ITK contain any functionality for finding the median of the
standard 9, 27, etc. neighborhood of a pixel?  I've been looking at
MedianImageFunction, but couldn't figure out how to use it for this
purpose.  Also the SmartNeighborhoodIterator uses similar
neighborhoods, but it doesn't have a method for calculating the median
as far as I can see.  Not that it's so hard to implement this myself,
but I just thought I'd check if what I'm looking for is already in
there somewhere first.
