Hi Cory, no problem, so I assume that there is no Wiener filter for noise-reducing...<br><br>melanie<br><br><div class="gmail_quote">2011/7/13 Cory Quammen <span dir="ltr"><<a href="mailto:cquammen@cs.unc.edu">cquammen@cs.unc.edu</a>></span><br>

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