[Insight-users] Question concerning level set term.

[tomtom]

Upps, missed your post.

So everything needed, concerning the level set function can be precomputed
for each "requirred" position by:

this->m_RequiredData.insert( "BackwardGradient" ); //forward gradient
this->m_RequiredData.insert( "ForwardGradient" ); //backward gradient
this->m_RequiredData.insert( "Value" ); //level set value
this->m_RequiredData.insert( "MeanCurvature" ); //curvature value
...

This is done prior to an evolution (iteration) step.
----------------------

Concerning  the Initalize*() Methods:

Initialize( const LevelSetInputIndexType& iP )  -  is called once, for each
position of the initial "seed" level set function, before the evolution
starts.

InitializeParameters()  -  gets called once prior to the first iteration of
the evolution?
The itk source code says: "Initialize parameters in the terms prior to an
iteration", which is a bit misleading.
----------------------

Thanks for your advices. Really helpful.
