Hi,<br><br>Thanks for your remarks.<br><br>I'll try to update the documentation some time later this week; you could also submit a patch to gerrit about the documentation...<br><br><a href="http://www.itk.org/Wiki/ITK_Release_4/New_Code_Contribution_Process">http://www.itk.org/Wiki/ITK_Release_4/New_Code_Contribution_Process</a><br>

So everything needed, concerning the level set function can be precomputed<br>
for each "requirred" position by:<br>
<br>
this->m_RequiredData.insert( "BackwardGradient" ); //forward gradient<br>
this->m_RequiredData.insert( "ForwardGradient" ); //backward gradient<br>
this->m_RequiredData.insert( "Value" ); //level set value<br>
this->m_RequiredData.insert( "MeanCurvature" ); //curvature value<br>
...<br>
<br>
This is done prior to an evolution (iteration) step.<br>
----------------------<br>
<br>
Concerning the Initalize*() Methods:<br>
<br>
Initialize( const LevelSetInputIndexType& iP ) - is called once, for each<br>
position of the initial "seed" level set function, before the evolution<br>
starts.<br>
<br>
InitializeParameters() - gets called once prior to the first iteration of<br>
the evolution?<br>
The itk source code says: "Initialize parameters in the terms prior to an<br>
iteration", which is a bit misleading.<br>
----------------------<br>
<br>
Thanks for your advices. Really helpful.<br>
<br>
