[Insight-users] Get global leveset image

[Arnaud Gelas]

Hi Hui,

If you use the ITKLevelSetsv4 module, you may want to have a look at  
the module ITKLevelSetsv4Visualization module.
In this module, you'd find classes and tests to display the evolution  
of a level-set interface in the 2D case, but also how to create a  
level-set image for any kind of representation.
These classes and examples are implementing Juan's comment, but using  
the new ITK level set framework.

To be able to use this code, you'd have to use the latest version  
available on the master branch using git, or wait couple of hours that  
the new release candidate tag is created.

If you work with the ITKLevelSets module, you'd need to implement  
similar thing based on this framework.

Best,
Arnaud
