[Insight-users] convolution - correlation

[Luis Ibanez]

Hi Isabelle,

Please look at the examples in the ITK Software Guide

       http://www.itk.org/ItkSoftwareGuide.pdf

the corresponding code is available in the directory:

         Insight/Examples/Filtering/
                     FFTDirectInverse.cxx
                     FFTDirectInverse2.cxx
                     FFTImageFilter.cxx
                     FFTImageFilterFourierDomainFiltering.cxx


Regards


    Luis
