Class legacy_Tracker

java.lang.Object
org.opencv.core.Algorithm
org.opencv.tracking.legacy_Tracker
Direct Known Subclasses:

public class legacy_Tracker extends Algorithm
Base abstract class for the long-term tracker:

  • Constructor Details

    • legacy_Tracker

      protected legacy_Tracker(long addr)

  • Method Details

    • __fromPtr__

      public static legacy_Tracker __fromPtr__(long addr)

    • init

      public boolean init(Mat image, Rect2d boundingBox)
      Initialize the tracker with a known bounding box that surrounded the target
      Parameters:
      image - The initial frame
      boundingBox - The initial bounding box
      Returns:
      True if initialization went succesfully, false otherwise

    • update

      public boolean update(Mat image, Rect2d boundingBox)
      Update the tracker, find the new most likely bounding box for the target
      Parameters:
      image - The current frame
      boundingBox - The bounding box that represent the new target location, if true was returned, not modified otherwise
      Returns:
      True means that target was located and false means that tracker cannot locate target in current frame. Note, that latter *does not* imply that tracker has failed, maybe target is indeed missing from the frame (say, out of sight)

    • finalize

      protected void finalize() throws Throwable
      Overrides:
      finalize in class Algorithm
      Throws:
      Throwable
