All Implemented Interfaces:

Runnable, Future<Void>, RunnableFuture<Void>

public class NearestNeighborsDistanceTask
extends BatchDistanceTask

A task that computes similarity of a set of faces by computing the distance of faces to an average face and then combining these values to get mutual similarity for all pairs.

The computation is accelerated by using multiple CPU cores concurrently. The exact computation parameters are taken from the BatchDistancePanel.
