Detailed Description

template<class TLabel, unsigned int VImageDimension>
class itk::LabelObject< TLabel, VImageDimension >

The base class for the representation of an labeled binary object in an image.

LabelObject is the base class to represent a labeled object in an image. It should be used associated with the LabelMap.

LabelObject store mainly 2 things: the label of the object, and a set of lines which are part of the object. No attribute is available in that class, so this class can be used as a base class to implement a label object with attribute, or when no attribute is needed (see the reconstruction filters for an example. If a simple attribute is needed, AttributeLabelObject can be used directly.

All the subclasses of LabelObject have to reinplement the CopyAttributesFrom() method.

Constructor & Destructor Documentation

template<class TLabel , unsigned int VImageDimension>
itk::LabelObject< TLabel, VImageDimension >::LabelObject (  )  [protected]

Member Function Documentation

template<class TLabel , unsigned int VImageDimension>
void itk::LabelObject< TLabel, VImageDimension >::AddIndex ( const IndexType idx  ) 

Add an index to the object. If the index is already in the object, the index can be found several time in the object.

template<class TLabel , unsigned int VImageDimension>
void itk::LabelObject< TLabel, VImageDimension >::AddLine ( const IndexType idx,
const LengthType length 
)

Add a new line to the object, without any check.

template<class TLabel , unsigned int VImageDimension>
void itk::LabelObject< TLabel, VImageDimension >::AddLine ( const LineType line  ) 

Add a new line to the object, without any check.

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

template<class TLabel , unsigned int VImageDimension>
void itk::LabelObject< TLabel, VImageDimension >::CopyAllFrom ( const Self src  ) 

Copy the lines, the label and the attributes from another node.

template<class TLabel , unsigned int VImageDimension>
virtual void itk::LabelObject< TLabel, VImageDimension >::CopyAttributesFrom ( const Self src  )  [virtual]

Copy the attributes of another node to this one

Reimplemented in itk::ShapeLabelObject< TLabel, VImageDimension >, and itk::StatisticsLabelObject< TLabel, VImageDimension >.

virtual Pointer itk::LightObject::CreateAnother (  )  const [virtual, inherited]
virtual void itk::LightObject::Delete (  )  [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

template<class TLabel , unsigned int VImageDimension>
bool itk::LabelObject< TLabel, VImageDimension >::Empty (  )  const
template<class TLabel , unsigned int VImageDimension>
static AttributeType itk::LabelObject< TLabel, VImageDimension >::GetAttributeFromName ( const std::string &  s  )  [static]

template<class TLabel , unsigned int VImageDimension>
const LabelType& itk::LabelObject< TLabel, VImageDimension >::GetLabel (  )  const

Set/Get the label associated with the object.
