Constructor & Destructor Documentation

§ MultiTracker_Alt()

cv::MultiTracker_Alt::MultiTracker_Alt ( )
inline

Constructor for Multitracker.

Member Function Documentation

§ addTarget()

bool cv::MultiTracker_Alt::addTarget ( InputArray  image,
const Rect2d boundingBox,
Ptr< Tracker tracker_algorithm 
)

Add a new target to a tracking-list and initialize the tracker with a know bounding box that surrounding the target.

Parameters
imageThe initial frame
boundingBoxThe initial boundig box of target
tracker_algorithmMulti-tracker algorithm
Returns
True if new target initialization went succesfully, false otherwise

§ update()

bool cv::MultiTracker_Alt::update ( InputArray  image)

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

Parameters
imageThe 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)
