Two-way nearest neighbor matching
Webapproximate nearest neighbor: a point p ∈ X is an e-approximate nearest neighbor of a query point q ∈X, if dist(p,q) ≤ (1+e)dist(p∗,q) where p∗ is the true nearest neighbor. The authors also propose the use of a priority queue to speed up the search in a tree by visiting tree nodes in order of their distance from the query point. Weblogical; if FALSE (default) return nearest points between all pairs, if TRUE, return nearest points between subsequent pairs.
