## Class MultiTracker

- java.lang.Object
- - org.opencv.core.Algorithm
  - - 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.
