Detailed Description

template<class TImageType, class TFeatureImageType>
class itk::VectorThresholdSegmentationLevelSetFunction< TImageType, TFeatureImageType >

This function is used in VectorThresholdSegmentationLevelSetImageFilter to segment structures in images based on the Mahalanobis distance.

SegmentationLevelSetFunction is a subclass of the generic LevelSetFunction.
It useful for segmentations based on intensity values in an image. It works by constructing a speed term (feature image) with positive values inside an intensity window (between a low and high threshold) and negative values outside that intensity window. The evolving level set front will lock onto regions that are at the edges of the intensity window.
Image $ f(x) $ is thresholded pixel by pixel using threshold $T$ according to the following formula.

\[ f(x) = T - MahalanobisDistance(x) \]

Member Function Documentation

template<class TImageType , class TFeatureImageType >
virtual void itk::VectorThresholdSegmentationLevelSetFunction< TImageType, TFeatureImageType >::CalculateSpeedImage ( ) [virtual]

This method must be defined in a subclass to implement a working function object. This method is called before the solver begins its work to produce the speed image used as the level set function's Propagation speed term. See LevelSetFunction for more information.

Reimplemented from itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType >.

template<class TImageType , class TFeatureImageType >
virtual::itk::LightObject::Pointer itk::VectorThresholdSegmentationLevelSetFunction< TImageType, TFeatureImageType >::CreateAnother ( void  ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

template<class TImageType , class TFeatureImageType >
virtual void itk::VectorThresholdSegmentationLevelSetFunction< TImageType, TFeatureImageType >::Initialize ( const RadiusType r) [inline, virtual]

This method creates the appropriate member variable operators for the level-set calculations. The argument to this function is a the radius necessary for performing the level-set calculations.
