Detailed Description

template<class TInputImage>
class itk::LiveWireImageFunction< TInputImage >

Implements livewire image segmentation of Barret and Mortensen.

LiveWireImageFunction implements the livewire segmentation algorithm of Barrett and Mortenson. This class naturally derives from the ImageFunction class where an N-D dimensional image is taken as input and the output consists of a path in that image.

Member Function Documentation

template<class TInputImage>

virtual OutputType::Pointer itk::LiveWireImageFunction< TInputImage >::Evaluate ( const PointType &  point ) const

inlinevirtual

Evaluate the function at specified Point position.

template<class TInputImage>

virtual OutputType::Pointer itk::LiveWireImageFunction< TInputImage >::EvaluateAtContinuousIndex ( const ContinuousIndexType &  cindex ) const

inlinevirtual

Evaluate the function at specified ContinousIndex position. Subclasses must provide this method.

template<class TInputImage >

LiveWireImageFunction< TInputImage >::OutputType::Pointer itk::LiveWireImageFunction< TInputImage >::EvaluateAtIndex ( const IndexType &  index ) const

virtual

Evaluate the function at specified Index position. Subclasses must provide this method.

template<class TInputImage>

itk::LiveWireImageFunction< TInputImage >::itkNewMacro

(

Self

)

Method for creation through the object factory.

template<class TInputImage>

template<class TInputImage>

itk::LiveWireImageFunction< TInputImage >::itkTypeMacro	(	LiveWireImageFunction< TInputImage >	,
		ImageFunction
	)

Run-time type information (and related methods).

template<class TInputImage >

void itk::LiveWireImageFunction< TInputImage >::PrintSelf ( std::ostream &  os, Indent  indent  ) const

protected

Standard "PrintSelf" method

template<class TInputImage >

void itk::LiveWireImageFunction< TInputImage >::SetInputImage ( const InputImageType *  ptr )

virtual

Set the input image.

Warning

this method caches BufferedRegion information. If the BufferedRegion has changed, user must call SetInputImage again to update cached values.

Initialize by setting the input image

Generate images for generating the weights from the input image
