[Insight-users] Multichannel images

[Jordi Inglada]

Hi Mike,

We are using itk::VectorImage<PixelType>, where PixelYype is a scalar 
one, and its OK since the number of channels needs not to be known at 
compile time as it is the case for itk::Image< itk::Vector<PixelType> >.

For the use of filters on a particular channel of your image, you can 
write an adaptor. See for instance the itk::VectorImageToImageAdaptor
which extracts the nth channel from a VectorImage.
