Detailed Description

template<class TInputImage, class TOutputImage, class TMaskImage = TInputImage>
class itk::ScalarConnectedComponentImageFilter< TInputImage, TOutputImage, TMaskImage >

A connected components filter that labels the objects in an arbitrary image. Two pixels are similar if they are within threshold of each other. Uses ConnectedComponentFunctorImageFilter.
