Detailed Description

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

This class generates a KdTree object with centroid information.

The KdTree object stores measurment vectors in a k-d tree structure that is a binary tree. The partition value is the median value of one of the k dimension (partition dimension). The partition dimension is determined by the spread of measurement values in each dimension. The partition dimension is the dimension has the widest spread. Our implementation of k-d tree doesn't have any construction or insertion logic. Users should use this class or the KdTreeGenerator class.

This class is derived from the KdTreeGenerator class. The only difference between this class and the KdTreeGenerator class is that the nonterminal node type of this class is KdTreeWeightedCentroidNonterminalNode and that of the KdTreeGenerator is KdTreeNonterminalNode. Therefore, the public interface is identical to each other. The nonterminal node generation routines differ.

To run this generator, users should provides the bucket size (SetBucketSize method) and the input sample (SetSample method). The Update method will run this generator. To get the resulting KdTree object, call the GetOutput method.

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. It is now obtained from the sample set as input. You may query this length using the function GetMeasurementVectorSize().
