[Insight-users] how to decide parameters: What visualization tool to use

[Luis Ibanez]

Hi Adithya


You can use:

               ImageViewer

The binary executable for Windows is at:
http://public.kitware.com/pub/itk/InsightApplicationsBin/ImageViewer.exe

and the source code is at:


     InsightApplications/ImageViewer


The tool will build in Windows, Linux, Mac... etc.


There are, of course, other tools,
but the ImageViewer should be enough for this.



     Regards,


         Luis
