#include <itkLevelSetEquationTermBase.h>

Detailed Description

template<typename TInputImage, typename TLevelSetContainer>
class itk::LevelSetEquationTermBase< TInputImage, TLevelSetContainer >

Abstract class to represents a term in the level-set evolution PDE.

Template Parameters

TInput	Input Image Type
TLevelSetContainer	Level set function container type

Evolving single level-set function \( \phi \) can be expressed as follows:

\[ \frac{\partial \phi(p)}{\partial \tau} = \sum\limits_{i=1}^{N} \alpha_{i} \cdot \omega_i(p) \]

where \(\omega_i\) is a term which could depend on the level-set function, the input image; and \(\alpha_i\) is a weight to balance the contribution of each term in the PDE.
