Detailed Description

template<typename Distance>
class cvflann::CompositeIndex< Distance >

This index builds a kd-tree index and a k-means index and performs nearest neighbour search both indexes. This gives a slight boost in search performance as some of the neighbours that are missed by one index are found by the other.
