[Insight-users] 3D convolution with custom matrix

[Cory Quammen]

Jothy,

ConvolutionImageFilter should handle 3D convolutions just fine. If you
encounter an error, please let me know. Also, if there is some
documentation that led you to conclude that the filter doesn't work
for 3D, please let me know so I can clarify it.

Be warned that ConvolutionImageFilter operates in the spatial domain,
so if your kernel is large, it will be quite slow. There will be a
FFT-based convolution filter in ITK v4 that will be much faster for
large kernels.

Thanks,
Cory
