ConvolutionImageFilter should handle 3D convolutions just fine. If you<br>
encounter an error, please let me know. Also, if there is some<br>
documentation that led you to conclude that the filter doesn't work<br>
for 3D, please let me know so I can clarify it.<br>
<br>
Be warned that ConvolutionImageFilter operates in the spatial domain,<br>
so if your kernel is large, it will be quite slow. There will be a<br>
FFT-based convolution filter in ITK v4 that will be much faster for<br>
large kernels.<br>
<br>
Thanks,<br>
Cory<br>
