[Insight-users] About GVF METHODS

[Luis Ibanez]

Hi Christian,


1) You could use seed points to initialize a level set,
     by using the FastMarching image filter.

     Please see the examples in the ITK Software Guide

               http://ItkSoftwareGuide.pdf

2) You may find these previous posting interesting:

3) I presume that what you have in mind is  to generate
    an Advection field with the GradientVectorFlow filter
    and then use that advection field in a LevelSet filter,
    such as the GeodesicaActiveContour one.




       Luis
