[Insight-users] Wiener Filter in ITK?

[Cory Quammen]

Melanie,

Sorry, my bias for microscopy images has shown through. I assumed you
meant a Wiener deconvolution filter. The Wiener filter that will be
added to ITK will be a Wiener deconvolution filter, not a
noise-reducing filter similar to wiener2 in MATLAB.
