Detailed Description

template<class TImageType, class TFeatureImageType = TImageType>
class itk::ShapePriorSegmentationLevelSetFunction< TImageType, TFeatureImageType >

This function is used in ShapePriorSegmentationLevelSetFilter to segment structures in an image based on user supplied edge potential map and shape model.

This class extends the basic LevelSetFunction with a shape prior term as developed in [1].

$ \zeta( \phi^{*} - \phi) $

where $ \phi^{*} $ is the signed distance function from a target shape and $ \zeta $ is a scalar constant.

The target shape signed distance function is supplied through a ShapeSignedDistanceFunction object.

This method allows the function to set its state before each iteration of the finite difference solver (image filter) that uses it. This is a thread-safe time to manipulate the object's state.

An example of how this can be used: the Anisotropic diffusion class of FiniteDifferenceFunctions use this method to pre-calculate an average gradient magnitude across the entire image region. This value is set in the function object and used by the ComputeUpdate methods that are called at each pixel as a constant.

virtual void itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType >::ReverseExpansionDirection (  )  [virtual, inherited]

Determines whether Positive or Negative speed terms will cause surface expansion. This method flips the sign of all of the speed, advection, etc terms. By convention, filters should be written so that POSITIVE speed terms cause surface expansion. Calling this method will toggle between the standard POSITIVE EXPANSION convention and the nonstandard NEGATIVE EXPANSION convention.

IMPORTANT: When adding terms to the level-set equation through subclassing you may need to override this function so that your new terms will be properly adjusted.
