[Insight-users] ConvolutionImageFilter only works with scalar images?

This seems to be a common theme... I also can't use
BinomialBlurImageFilter on an image of type

itk::Image<itk::CovariantVector<unsigned char, 3>, 2>

Is there and ITK equivalent of
vtkImageExtractComponents/vtkImageAppendComponents that will let me
'disassemble', operate on, and then 'reassemble' this type of image
one "channel" at a time?
