Convolution Filter 3d Image


I want to filter my 3d Image with a kernel(9x9x9 for example).
What is the best function to use for this? ConvolutionImageFilter?

Thanks a lot for your help,

ConvolutionImageFilter is quite general and therefore not especially fast. And the kernel you want to use is quite big too. ITK might already implement what you want to do in a more specialized filter. What are you trying to accomplish?
