Detailed Description

template<typename TImageType, typename TFeatureImageType = TImageType>
class itk::GeodesicActiveContourShapePriorLevelSetFunction< TImageType, TFeatureImageType >

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

IMPORTANT: The LevelSetFunction, SegmentationLevelSetFunction and ShapePriorSegmentationLevelSetFunction classes contain additional information necessary to gain full understanding of how to use this function.

GeodesicActiveContourShapePriorLevelSetFunction is a subclass of the generic LevelSetFunction. It is used to segment structures in an image based on a user supplied edge potential map $ g(I) $ , which has values close to zero in regions near edges (or high image gradient) and values close to one in regions with relatively constant intensity. Typically, the edge potential map is a function of the gradient, for example:

$g(I) = 1 / ( 1 + | (\nabla * G)(I)| )$

$g(I) = \exp^{-|(\nabla * G)(I)|}$

where $ I $ is image intensity and $(\nabla * G)$ is the derivative of Gaussian operator.

The edge potential image is set via the SetFeatureImage() method.

In this function both the propagation term $P(\mathbf{x})$ and the curvature spatial modifier term $Z(\mathbf{x})$ are taken directly from the edge potential image such that:

$P(\mathbf{x}) = g(\mathbf{x})$

$Z(\mathbf{x}) = g(\mathbf{x})$

An advection term $\mathbf{A}(\mathbf{x})$ is constructed from the negative gradient of the edge potential image.

$\mathbf{A}(\mathbf{x}) = -\nabla g(\mathbf{x})$

This term behaves like a doublet attracting the contour to the edges.

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. Typically, the shape is a function of a set of parameters.
