Syntax

public abstract class Tracker : Algorithm, ICvPtrHolder

Constructors

Tracker(Ptr)

Declaration

protected Tracker(Ptr ptrObj)

Parameters

Type	Name	Description
Ptr	ptrObj

Methods

DisposeManaged()

Releases managed resources

Declaration

protected override void DisposeManaged()

Overrides

DisposableObject.DisposeManaged()

Init(Mat, Rect)

Initialize the tracker with a know bounding box that surrounding the target

Declaration

public void Init(Mat image, Rect boundingBox)

Parameters

Type	Name	Description
Mat	image	The initial frame
OpenCvSharp.Rect	boundingBox	The initial bounding box

Update(Mat, ref Rect)

Update the tracker, find the new most likely bounding box for the target

Declaration

public bool Update(Mat image, ref Rect boundingBox)

Parameters

Type	Name	Description
Mat	image	The current frame
OpenCvSharp.Rect	boundingBox	The bounding box that represent the new target location, if true was returned, not modified otherwise

Returns

Type	Description
System.Boolean	True means that target was located and false means that tracker cannot locate target 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)
