- * Add the capability to change the number of channel when operation on
- * VectorImage compared to the itk::UnaryFunctorImageFilter
- *
- * The number of channel is provided by the functor: TFunction::GetOutputSize. If
- * this number is lower or equal to zero, the behavior of the itk::UnaryFunctorImageFilter
- * remains unchanged.
