Detailed Description

template<class TSample>
class itk::Statistics::KdTree< TSample >::NearestNeighbors

data structure for storing k-nearest neighbor search result (k number of Neighbors)

This class stores the instance identifiers and the distance values of k-nearest neighbors. We can also query the farthest neighbor's distance from the query point using the GetLargestDistance method.
