Inheritance diagram for itk::GeodesicActiveContourShapePriorLevelSetFunction< TImageType, TFeatureImageType >:


, 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:
where
is image intensity and
is the derivative of Gaussian operator.
The edge potential image is set via the SetFeatureImage() method.
In this function both the propagation term
and the curvature spatial modifier term
are taken directly from the edge potential image such that:
An advection term
is constructed from the negative gradient of the edge potential image.
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].

where
is the signed distance function from a target shape and
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.
