itk::ConnectedComponentImageFilter< TInputImage, TOutputImage, TMaskImage > Class Template Reference

#include <itkConnectedComponentImageFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage, typename TMaskImage = TInputImage>
class itk::ConnectedComponentImageFilter< TInputImage, TOutputImage, TMaskImage >

Label the objects in a binary image.

ConnectedComponentImageFilter labels the objects in a binary image (non-zero pixels are considered to be objects, zero-valued pixels are considered to be background). Each distinct object is assigned a unique label. The filter experiments with some improvements to the existing implementation, and is based on run length encoding along raster lines. If the output background value is set to zero (the default), the final object labels start with 1 and are consecutive. If the output background is set to a non-zero value (by calling the SetBackgroundValue() routine of the filter), the final labels start at 0, and remain consecutive except for skipping the background value as needed. Objects that are reached earlier by a raster order scan have a lower label. This is different to the behaviour of the original connected component image filter which did not produce consecutive labels or impose any particular ordering.

After the filter is executed, ObjectCount holds the number of connected components.

ConnectedComponentImageFilter will produce all of the output. Therefore it must provide an implementation of EnlargeOutputRequestedRegion().

◆ FullyConnectedOn()

template<typename TInputImage , typename TOutputImage , typename TMaskImage = TInputImage>
virtual void itk::ConnectedComponentImageFilter< TInputImage, TOutputImage, TMaskImage >::FullyConnectedOn ( )
virtual

Set/Get whether the connected components are defined strictly by face connectivity or by face+edge+vertex connectivity. Default is FullyConnectedOff. For objects that are 1 pixel wide, use FullyConnectedOn.

◆ GenerateData()

template<typename TInputImage , typename TOutputImage , typename TMaskImage = TInputImage>
void itk::ConnectedComponentImageFilter< TInputImage, TOutputImage, TMaskImage >::GenerateData ( )
overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.
