Detailed Description

template<typename TTermContainer>
class itk::LevelSetEquationContainer< TTermContainer >

Class for holding a set of level set equations (PDEs).

Template Parameters
TTermContainerContainer holding the terms in a level set equation

Evolving level-set functions $\left\{ \phi_j \right\}_{j=1}^{M}$ can be expressed as follows:

\begin{eqnarray*} \frac{\partial \phi_1(p)}{\partial \tau} &=& \sum\limits_{i=1}^{N_1} \alpha_{i1} \cdot \omega_{i1}(p) \\ \frac{\partial \phi_2(p)}{\partial \tau} &=& \sum\limits_{i=1}^{N_2} \alpha_{i2} \cdot \omega_{i2}(p) \\ & \vdots & \\ \frac{\partial \phi_M(p)}{\partial \tau} &=& \sum\limits_{i=1}^{N_M} \alpha_{iM} \cdot \omega_{iM}(p) \end{eqnarray*}

where $\omega_{iM}$ is a term which could depend on any of the level-set functions $\left\{ \phi_j \right\}_{j=1}^{M}$ , the input image, and $\alpha_{iM}$ is a weight to balance the contribution of each term in the PDE.

Each equation of this system of equation (PDE) is referred as an equation in the level-set framework. Each equation $ equation_{j} $ contributes to the evolution of the level-set function $ \phi_j $.
