[Insight-users] Current state of "Active Contours without edges" in Review folder? - Example?

[Oleksandr Dzyubak]

Hi Kishore,

You probably have some box with ITK installed.
If you do, you could compile examples from ITK which
comes in separate package "InsightApplications" (if you have not done so 
yet).
Once successfully compiled, under directory
~/InsightApplications/ConvertBetweenFileFormats you can find the executable
ConvertBetweenFileFormats.

The rest is quite simple. If you want to use Paraview, do as below

./ConvertBetweenFileFormats image.nii image.mhd

The second operand could be change to whatever your favorite format is.
