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.
