Inheritance diagram for itk::Statistics::KdTreeNode< TSample >:

Detailed Description

template<typename TSample>
class itk::Statistics::KdTreeNode< TSample >

This class defines the interface of its derived classes.

The methods defined in this class are a superset of the methods defined in its subclases. Therefore, the subclasses implements only part of the methods. The template argument, TSample, can be any subclass of the Sample class.

There are two categories for the subclasses, terminal and nonterminal nodes. The terminal nodes stores the instance identifiers beloging to them, while the nonterminal nodes don't. Therefore, the AddInstanceIdentifier and the GetInstanceIdentifier have meaning only with the terminal ones. The terminal nodes don't have any child (left or right). For terminal nodes, the GetParameters method is void.

Recent API changes: The static const macro to get the length of a measurement vector, MeasurementVectorSize has been removed to allow the length of a measurement vector to be specified at run time. The typedef for CentroidType has been changed from Array to FixedArray.
