Detailed Description

template<class TInputImage, class TOutputImage, class TFunctor, class TMaskImage = TInputImage>
class itk::ConnectedComponentFunctorImageFilter< TInputImage, TOutputImage, TFunctor, TMaskImage >

A generic connected components filter that labels the objects in an artibitrary image.

ConnectedComponentFunctorImageFilter labels the objects in an arbitrary image. Each distinct object is assigned a unique label. The filter makes three passes through the image. The first pass initializes the output. The second pass labels each foreground pixel such that all the pixels associated with an object either have the same label or have had their labels entered into a equivalency table. The third pass through the image flattens the equivalency table such that all pixels for an object have the same label.

The functor specifies the criteria to join neighboring pixels. For example a simple intensity threshold difference might be used for scalar imagery.

The final object labels are in no particular order (and some object labels may not be used on the final objects). You can reorder the labels such that object labels are consecutive and sorted based on object size by passing the output of this filter to a RelabelComponentImageFilter.
