ITK doesn't have the built-in notion of transfer functions.
This is mostly a visualization concept. You could however easily
implement such functionalities by using the itk::UnaryFunctorFilter
in the case of the pure intensity color mapping, and by using the
itk::BinaryFunctionImageFilter for the combined intensity & gradient
You may find interesting to look at the use of this filter in the
WatershedSegmentation1.cxx example in
You could also combine a set of RecursiveGradientImageFilter
in order to feed a multi-input functor image filter.
ImageAdaptors are also a good option for implementing transfer
fuctions, in particular if you are concerned about memory consumption.
For a discussion on the use of ImageAdaptors, you may want to look
at the SoftwareGuide
Chapter 12, pdf-page 521.
