Detailed Description

template<class TInputImage, class 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.
