Hi Ashwath,
Thank you for further explaining your objective -- this makes it
easier for the mailing list to offer you advice.
The steps you suggest seem correct. The only advice I may offer is
that with the ITK registration framework, registration and resampling
are one and the same step (i.e. the output of the registration process
is a resampled moving image):
1. Registration and resampling
2. Image fusion
3. Fused image display
You are correct that ITK can perform 1 and 2, and VTK (plus a chosen
GUI framework, like QT) can perform 3.
For step one, please read the ITK Software Guide (chapter 8, pages 315-501):
http://www.itk.org/ItkSoftwareGuide.pdf
Also, you can find many relevant registration examples with the ITK
source code or on the wiki:
http://www.itk.org/Wiki/ITK/Examples/Included/Registration
For step two, you have many options. The following links may help:
http://www.imagefusion.org/
http://www.imagefusion.org/publications/reports/piella-TR-PNA-R0211.pdf
http://www.insight-journal.org/browse/publication/103
For step three, you can find some examples here:

Hope this helps.
Regards, Dan
