Detailed Description

template<typename TImageType>
class itk::LevelSetFunction< TImageType >

The LevelSetFunction class is a generic function object which can be used to create a level set method filter when combined with an appropriate finite difference image filter. (See FiniteDifferenceImageFilter.)

LevelSetFunction implements a generic level set function. This function is an expanded form of the basic equation developed in [1].

\(\phi_{t} + \alpha \stackrel{\rightharpoonup}{A}(\mathbf{x})\cdot\nabla\phi + \beta P(\mathbf{x})\mid\nabla\phi\mid = \gamma Z(\mathbf{x})\kappa\mid\nabla\phi\mid\)

where \( \stackrel{\rightharpoonup}{A} \) is an advection term, \( P \) is a propagation (growth) term, and \( Z \) is a spatial modifier term for the mean curvature \( \kappa \). \( \alpha \), \( \beta \), and \( \gamma \) are all scalar constants.

Terms in the equation above are supplied through virtual methods, which must be subclassed to complete an implementation. Terms can be eliminated from the equation by setting the corresponding constants to zero. A wide variety of level set methods can be implemented by subclassing this basic equation.

In ITK, the usual sign convention is that the INSIDE of a surface contains NEGATIVE values and the OUTSIDE of the surface contains POSITIVE values.

Warning
You MUST call Initialize() in the constructor of subclasses of this object to set it up properly to do level-set Calculations. The argument that you pass Initialize is the radius of the neighborhood needed to perform the calculations. If your subclass does not do any additional neighborhood processing, then the default radius should be 1 in each direction.

◆ ComputeGlobalTimeStep()

template<typename TImageType >
TimeStepType itk::LevelSetFunction< TImageType >::ComputeGlobalTimeStep ( void *  GlobalData) const
overridevirtual

Computes the time step for an update given a global data structure. The data used in the computation may take different forms depending on the nature of the equations. This global data cannot be kept in the instance of the equation object itself since the equation object must remain stateless for thread safety. The global data is therefore managed for each thread by the finite difference solver filters.

Implements itk::FiniteDifferenceFunction< TImageType >.

◆ GetGlobalDataPointer()

template<typename TImageType >
void * itk::LevelSetFunction< TImageType >::GetGlobalDataPointer ( ) const
inlineoverridevirtual

Returns a pointer to a global data structure that is passed to this object from the solver at each calculation. The idea is that the solver holds the state of any global values needed to calculate the time step, while the equation object performs the actual calculations. The global data should also be initialized in this method. Global data can be used for caching any values used or reused by the FunctionObject. Each thread should receive its own global data struct.
