Detailed Description

template<class TLabelObject>
class itk::LabelMap< TLabelObject >

Templated n-dimensional image to store labeled objects.

LabelMap is an image class specialized in storing the labeled images. It represent the image in a different way than itk::Image. Instead of storing the content of the image in an array of pixels values, it store the a collection of labeled objects, and a background value. This way of storing the content of the image allow an easy and efficient manipulation of the objects in the image.

The LabelMap shares a lot of methods with the itk::Image class. it make it usable as input or output of the itk::ImageToImageFilter for example. However the methods don't have the same complexity in the 2 classes, because of the different way to store the data. GetPixel() is run in constant time for example in itk::Image, but have a worst case complexity of O(L), where L is the number of lines in the image (imageSize[1] * imageSize[2] for a 3D image).

To iterate over the LabelObjects in the map, use:

for(unsigned int i = 0; i < filter->GetOutput()->GetNumberOfLabelObjects(); ++i)
  {
  FilterType::OutputImageType::LabelObjectType* labelObject =
    filter->GetOutput()->GetNthLabelObject(i);
  }

void itk::LabelMap< TLabelObject >::AddLabelObject ( LabelObjectType * labelObject )

Add a label object to the image. If a label object already has the label, it is overiden.

template<class TLabelObject >

void itk::LabelMap< TLabelObject >::AddPixel	(	const IndexType &	idx,
		const LabelType &	label
	)

Add index idx to the label object whose label is label. If no label object has the label label, the corresponding label object is created. The worst case complexity of this method is O(L) where L is the number of lines in the image. However, the execution time will be quite low if the pixels are set in the image in raster mode.

virtual void itk::LabelMap< TLabelObject >::Allocate ( )

template<class TLabelObject >

virtual::itk::LightObject::Pointer itk::LabelMap< TLabelObject >::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 TLabelObject >

const LabelObjectType* itk::LabelMap< TLabelObject >::GetLabelObject ( const LabelType & label ) const

Return the LabelObject with the label given in parameter. This method thorws an exception if the label doesn't exist in this image, or if the label is the background one.

template<class TLabelObject >

LabelObjectType* itk::LabelMap< TLabelObject >::GetLabelObject ( const IndexType & idx ) const

template<class TLabelObject >

const LabelObjectType* itk::LabelMap< TLabelObject >::GetNthLabelObject ( const SizeValueType & pos ) const

template<class TLabelObject >

const LabelType& itk::LabelMap< TLabelObject >::GetPixel ( const IndexType & idx ) const

Return the pixel value at a given index in the image. If the given index is contained in several objects, only the smallest label of those objects is returned. This method has a worst case complexity of O(L) where L is the number of lines in the image - use it with care.

template<class TLabelObject >

virtual void itk::LabelMap< TLabelObject >::Graft ( const DataObject * data )

virtual

Graft the data and information from one image to another. This is a convenience method to setup a second image with all the meta information of another image and use the same pixel container. Note that this method is different than just using two SmartPointers to the same image since separate DataObjects are still maintained. This method is similar to ImageSource::GraftOutput(). The implementation in ImageBase simply calls CopyInformation() and copies the region ivars. Subclasses of ImageBase are responsible for copying the pixel container.

Reimplemented from itk::ImageBase< TLabelObject::ImageDimension >.

template<class TLabelObject >

bool itk::LabelMap< TLabelObject >::HasLabel ( const LabelType label ) const

Return true is the image contains the label given in parameter and false otherwise. If the label is the background one, true is also returned, so this method may not be a good enough test before calling GetLabelObject().

template<class TLabelObject >

Remove a label object.

void itk::LabelMap< TLabelObject >::SetLine	(	const IndexType &	idx,

Set a full line in the image. If no label object has this label in the image, a new object is created. If a label object already exist with that label, the line is added to it WITHOUT any check - it means that if the label object may contain several time the same pixel after have run that method. This method runs in constant time.

template<class TLabelObject >

void itk::LabelMap< TLabelObject >::SetPixel	(	const IndexType &	idx,
		const LabelType &	label
	)

Set the pixel value at a given index in the image.

As for itk::Image, this method ensure that the pixel at the position idx has a unique value.

The complexity of this method is at best O(L) where L is the number of lines in the image - usit with care.
