Member Function Documentation

add() [1/4]

bool cv::MultiTracker::add	(	const Mat &	image,
		const Rect2d &	boundingBox
	)

Add a new object to be tracked. The defaultAlgorithm will be used the newly added tracker.

Parameters

image	input image
boundingBox	a rectangle represents ROI of the tracked object

add() [2/4]

bool cv::MultiTracker::add	(	const String &	trackerType,
		const Mat &	image,
		const Rect2d &	boundingBox
	)

Add a new object to be tracked.

Parameters

trackerType	the name of the tracker algorithm to be used
image	input image
boundingBox	a rectangle represents ROI of the tracked object

add() [3/4]

bool cv::MultiTracker::add	(	const String &	trackerType,
		const Mat &	image,
		std::vector< Rect2d >	boundingBox
	)

Add a set of objects to be tracked.

Parameters

trackerType	the name of the tracker algorithm to be used
image	input image
boundingBox	list of the tracked objects

add() [4/4]

bool cv::MultiTracker::add	(	const Mat &	image,
		std::vector< Rect2d >	boundingBox
	)

Add a set of objects to be tracked using the defaultAlgorithm tracker.

Parameters

image	input image
boundingBox	list of the tracked objects

update() [1/2]

bool cv::MultiTracker::update

(

const Mat &

image

)

Update the current tracking status. The result will be saved in the internal storage.

Parameters

update() [2/2]

bool cv::MultiTracker::update	(	const Mat &	image,
		std::vector< Rect2d > &	boundingBox
	)

Update the current tracking status.

Parameters

image	input image
boundingBox	the tracking result, represent a list of ROIs of the tracked objects.
