Detailed Description

Base abstract class for the long-term Multi Object Trackers:

See also: Tracker, MultiTrackerTLD

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 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()

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

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)
