Hello everyone,<br>
<br>
I have studied the implementation of the internal and external Chan and Vese<br>
Term and the corresponding Chan and Vese paper and to be honest, I am a bit<br>
confused.<br>
<br>
As far as I understand things right now, the itk::Internal... and<br>
itk::External... are not the same as in the paper. (Especially the naming<br>
seems to be strange. Aren't booth terms part of the external term, regarding<br>
the paper?<br></blockquote><div><br>These terms are actually a generalization of the Chan and Vese paper for N level sets.<br>I am not sure to totally understand your question here... Can you be more clear here, please?<br>

Where does the internal energy come from? Or isn't it included at all, and<br>
the curve moves just until the criterion has reached a "somehow" steady<br>
state? (For synthetic images this may work, but not for real data.)<br></blockquote><div><br>Without the code, it is difficult to know what you are doing.<br>Anyway, in the new framework users are responsible to gather all terms in the term container. Make sure there is a the internal term, the external term and the curvature term.<br>
There is actually one test in the level set module which demonstrate its application (can' tell you which one right now).<br> <br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Any remarks would be helpful. Thanks.<br></blockquote><div><br><br>If you share the code with me, I can have a look and tell you what could be wrong, or track down potential bugs if any...<br><br>Best,<br>Arnaud<br><br> </div>
