int SetTrackMarkers (MarkerDetector< M > &marker_detector, Camera *cam, Pose &pose, IplImage *image=0)
 Set new markers to be tracked for MarkerDetector Sometimes the MultiMarker implementation knows more about marker locations compared to MarkerDetector . Then this method can be used to reset the internal state of MarkerDetector for tracking also these markers.
