                                             Tracker tracker_algorithm)

\brief Add a new target to a tracking-list and initialize the tracker with a known bounding box that surrounded the target

Parameters:

image - The initial frame

boundingBox - The initial bounding box of target

tracker_algorithm - Multi-tracker algorithm

Returns:

True if new target initialization went succesfully, false otherwise

update

@Cast(value="bool")
public boolean update(@ByVal
                                          Mat image)

\brief Update all trackers from the tracking-list, find a new most likely bounding boxes for the targets

Parameters:

image - The current frame

Returns:

True means that all targets were located and false means that tracker couldn't locate one of the targets 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)
