Member Function Documentation

init()

virtual CV_WRAP void cv::Tracker::init ( InputArray  image, const Rect &  boundingBox  )

pure virtual

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

Parameters

image	The initial frame
boundingBox	The initial bounding box

update()

virtual CV_WRAP bool cv::Tracker::update ( InputArray  image, CV_OUT Rect &  boundingBox  )

pure virtual

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

Parameters

image	The current frame
boundingBox	The 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)
