Detailed Description

template<class TInputImage, class TOutputImage>
class itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >

The purpose of this program is to produce the connected components for any input binary image of dimensionality n.

The program does a forward pass line by line through the entire image. Each cell in the foreground is assigned the same label value as cells in its neighborhood. If there is no label among the cells in its neighborhood, a new label value is assigned to the cell. This means that this cell belongs to a different connected component. We set up an equivalence table for each label to indicate the equivalence of the labels stored in the table. After the forward pass goes through the entire image, we merge the different connected components corresponding to the equivalence labels in the table. We implement this strategy in function GenerateData().

There are two options in the program. 1. Take an nD binary image as input, and produce an nD gray image, where intensity indicates label assigned to a connected component. 2. Take an nD binary image and a set of seed points as input, and output an nD binary image containing the cells connected to the seeds. For option 2, users need to assign the member variable std::list<IndexType> m_Seeds before calling function GenerateData().

Member Function Documentation

template<class TInputImage , class TOutputImage >
virtual::itk::LightObject::Pointer itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >::CreateAnother ( void  ) const [virtual]

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.

Reimplemented from itk::Object.

void itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >::GenerateData ( ) [protected, virtual]

Standard pipeline method.

template<class TInputImage , class TOutputImage >
static Pointer itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage >
void itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >::operator= ( const Self ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.

void itk::HardConnectedComponentImageFilter< TInputImage, TOutputImage >::PrintSelf ( std::ostream &  os,

) const [inline, protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
