#include <itkConnectedComponentFunctorImageFilter.h>
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.

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.

Get the functor object. The functor is returned by reference. (Functors do not have to derive from itk::LightObject, so they do not necessarily have a reference count. So we cannot return a SmartPointer.)

Set the functor object. This replaces the current Functor with a copy of the specified Functor. This allows the user to specify a functor that has ivars set differently than the default functor. This method requires an operator!=() be defined on the functor (or the compiler's default implementation of operator!=() being appropriate).
