Detailed Description#

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

Constructor & Destructor Documentation#

MultiTracker_Alt()#

cv::legacy::MultiTracker_Alt::MultiTracker_Alt()

Constructor for Multitracker.

Member Function Documentation#

addTarget()#

bool cv::legacy::MultiTracker_Alt::addTarget(
InputArray image,
const Rect2d & boundingBox,
Ptr< legacy::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::legacy::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)
