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.

The pixels locations belonging to the LabelObject can be obtained using:

 for(unsigned int pixelId = 0; pixelId < labelObject->Size(); pixelId++)
   {
   std::cout << labelObject->GetIndex(pixelId);
   }
