__fromPtr__
public static 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 frameboundingBox
- 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 frameboundingBox
- 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)
