Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::RelabelComponentImageFilter< TInputImage, TOutputImage >

Relabel the components in an image such that consecutive labels are used.

RelabelComponentImageFilter remaps the labels associated with the objects in an image (as from the output of ConnectedComponentImageFilter) such that the label numbers are consecutive with no gaps between the label numbers used. By default, the relabeling will also sort the labels based on the size of the object: the largest object will have label #1, the second largest will have label #2, etc. If two labels have the same size their initial order is kept. The sorting by size can be disabled using SetSortByObjectSize.

Label #0 is assumed to be the background and is left unaltered by the relabeling.

RelabelComponentImageFilter is typically used on the output of the ConnectedComponentImageFilter for those applications that want to extract the largest object or the "k" largest objects. Any particular object can be extracted from the relabeled output using a BinaryThresholdImageFilter. A group of objects can be extracted from the relabled output using a ThresholdImageFilter.

Once all the objects are relabeled, the application can query the number of objects and the size of each object. Object sizes are returned in a vector. The size of the background is not calculated. So the size of object #1 is GetSizeOfObjectsInPixels()[0], the size of object #2 is GetSizeOfObjectsInPixels()[1], etc.

If user sets a minimum object size, all objects with fewer pixels than the minimum will be discarded, so that the number of objects reported will be only those remaining. The GetOriginalNumberOfObjects method can be called to find out how many objects were present before the small ones were discarded.

RelabelComponentImageFilter can be run as an "in place" filter, where it will overwrite its output. The default is run out of place (or generate a separate output). "In place" operation can be controlled via methods in the superclass, InPlaceImageFilter::InPlaceOn() and InPlaceImageFilter::InPlaceOff().

virtual::itk::LightObject::Pointer itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::CreateAnother ( ) 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.

Reimplemented from itk::Object.

template<typename TInputImage , typename TOutputImage >
void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GenerateData ( )

Standard pipeline method.

template<typename TInputImage , typename TOutputImage >
void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( )

RelabelComponentImageFilter needs the entire input. Therefore it must provide an implementation GenerateInputRequestedRegion().

template<typename TInputImage , typename TOutputImage >
virtual ObjectSizeType itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetMinimumObjectSize ( ) const
virtual

Get the caller-defined minimum size of an object in pixels. If the caller has not set the minimum, 0 will be returned, which is to be interpreted as meaning that no minimum exists, and all objects in the original label map will be passed through to the output.

Get the original number of objects in the image before small objects were discarded. This information is only valid after the filter has executed. If the caller has not specified a minimum object size, OriginalNumberOfObjects is the same as NumberOfObjects.

template<typename TInputImage , typename TOutputImage >
float itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::GetSizeOfObjectInPhysicalUnits ( LabelType  obj) const
inline

Get the size of a particular object in physical space (in units of pixel size). This information is only valid after the filter has executed. Size of the background (object #0) is not calculated.

virtual void itk::RelabelComponentImageFilter< TInputImage, TOutputImage >::SetMinimumObjectSize ( ObjectSizeType  _arg)

Set the minimum size in pixels for an object. All objects smaller than this size will be discarded and will not appear in the output label map. NumberOfObjects will count only the objects whose pixel counts are greater than or equal to the minimum size. Call GetOriginalNumberOfObjects to find out how many objects were present in the original label map.
