Antw: [Insight-users] original slice overlapped with the segmented ROI -> FLTKImageViewer

[Karthik Krishnan]

If you are writing inserting this in your own code, you could easily write a blend functor that derives from BinaryFunctorImageFilter and gives an output aX + (1-a)Y.
(See Code/BasicFilters/itkAddImageFilter.h).

In 3D, you could do this with volume rendering, choosing an appropriate transfer function so you can see both volumes. You could colour map the result for a nice look. (VolView has a filter "MergeVolumes" in the Utility section that should do this for you in 2D and 3D).
