org.opencv.tracking.MultiTracker

public class MultiTracker
extends Algorithm

This class is used to track multiple objects using the specified tracker algorithm. The %MultiTracker is naive implementation of multiple object tracking. It process the tracked objects independently without any optimization accross the tracked objects.
