I am a collage student studying vtk and itk. Now I have two slices of vtkImageData, what method or class can I use to transform these two vtkImageData to itk::image type \<unsigned , 3\> and put into MorphologicalContourInterpolator.  
Thanks for your help!

My image type is :

(image1 is a 2 binary image, I want to use image1 or image2)

The target type is:
