Detailed Description

template<typename TInput, typename TLevelSetContainer>
class itk::LevelSetEquationChanAndVeseInternalTerm< TInput, TLevelSetContainer >

Class to represent the internal energy Chan And Vese term.

\[ \delta_{\epsilon}\left( \phi_{k} \left( p \right) \right) \cdot \left\| I\left( p \right) - \mu_{in} \right\|^2 \cdot \]

\( \delta_{epsilon} \) is a regularized dirac function,
\( k \) is the current level-set id,
\( I\left( p \right) \) is the pixel value at the given location \( p \),
\( \mu_{in} \) is the internal mean intensity.

Template Parameters

TInput	Input Image Type
TLevelSetContainer	Level set function container type
