    /**
     * the TLD (Tracking, learning and detection) tracker
     *
     * TLD is a novel tracking framework that explicitly decomposes the long-term tracking task into
     * tracking, learning and detection.
     *
     * The tracker follows the object from frame to frame. The detector localizes all appearances that
     * have been observed so far and corrects the tracker if necessary. The learning estimates detector's
     * errors and updates it to avoid these errors in the future. The implementation is based on CITE: TLD .
     *
     * The Median Flow algorithm (see cv::TrackerMedianFlow) was chosen as a tracking component in this
     * implementation, following authors. The tracker is supposed to be able to handle rapid motions, partial
     * occlusions, object absence etc.
