[Insight-users] Problem with itkConvolutionImageFilter from git

Fri Sep 16 10:39:39 EDT 2011

Yes,I can switch to ITk4.0. Since my program is not dependent on ITK till
now.

(But I am more interested in the fft based convolution filters. If you have
your fft based filter codes I could test them with ITK4.0, before you push
it to git.)

Thanks

Jothy
