Member Function Documentation

◆ init()

virtual void cv::Tracker::init ( InputArray  image,
const Rect boundingBox 
)
pure virtual
Python:
None=cv.Tracker.init(image, boundingBox)

Initialize the tracker with a known bounding box that surrounded the target.

Parameters
imageThe initial frame
boundingBoxThe initial bounding box

◆ update()

virtual bool cv::Tracker::update ( InputArray  image,
Rect boundingBox 
)
pure virtual
Python:
retval, boundingBox=cv.Tracker.update(image)

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

Parameters
imageThe current frame
boundingBoxThe bounding box that represent the new target location, if true was returned, not modified otherwise
Returns
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)
