Detailed Description

template<class TInputImage, class TOutputImage = LabelMap< LabelObject< SizeValueType, ::itk::GetImageDimension< TInputImage >::ImageDimension > >>
class itk::BinaryImageToLabelMapFilter< TInputImage, TOutputImage >

Label the connected components in a binary image and produce a collection of label objects.

BinaryImageToLabelMapFilter labels the objects in a binary image. Each distinct object is assigned a unique label. The final object labels start with 1 and are consecutive. Objects that are reached earlier by a raster order scan have a lower label.

The GetOutput() function of this class returns an itk::LabelMap.
