<br>Sharath,<br><br>Also, since your goal here seems to be visualization,<br>you may want to consider the following options:<br><br><br>A) VTK 3D Widgets, in particular<br><a href="http://www.vtk.org/doc/nightly/html/classvtkCheckerboardWidget.html">http://www.vtk.org/doc/nightly/html/classvtkCheckerboardWidget.html</a><br>
<a href="http://www.vtk.org/doc/nightly/html/classvtkRectilinearWipeWidget.html">http://www.vtk.org/doc/nightly/html/classvtkRectilinearWipeWidget.html</a><br><br> They were designed for evaluating the results of image registration.<br>
<br><br>B) VV, and application that you can download from<br><a href="http://www.midasjournal.org/browse/publication/617">http://www.midasjournal.org/browse/publication/617</a> <br> or from<br><a href="http://www.creatis.insa-lyon.fr/rio/vv">http://www.creatis.insa-lyon.fr/rio/vv</a><br>
<br> VV offers a good set of options for comparing images<br> after registration, and it is very easy to use.<br><br><br><br>C) Slicer, that you can download from<br> <a href="http://www.slicer.org">http://www.slicer.org</a><br>
You can load multiple images into slicer and overlap them<br>using transparency, color encoding and checkerboards.<br><br><br> Regards,<br><br><br> Luis<br><br><br>------------------------------------------------------------<br>
