    /**
     * the GOTURN (Generic Object Tracking Using Regression Networks) tracker
     *
     * GOTURN (CITE: GOTURN) is kind of trackers based on Convolutional Neural Networks (CNN). While taking all advantages of CNN trackers,
     * GOTURN is much faster due to offline training without online fine-tuning nature.
     * GOTURN tracker addresses the problem of single target tracking: given a bounding box label of an object in the first frame of the video,
     * we track that object through the rest of the video. NOTE: Current method of GOTURN does not handle occlusions; however, it is fairly
     * robust to viewpoint changes, lighting changes, and deformations.
     * Inputs of GOTURN are two RGB patches representing Target and Search patches resized to 227x227.
     * Outputs of GOTURN are predicted bounding box coordinates, relative to Search patch coordinate system, in format X1,Y1,X2,Y2.
     * Original paper is here: <http://davheld.github.io/GOTURN/GOTURN.pdf>
     * As long as original authors implementation: <https://github.com/davheld/GOTURN#train-the-tracker>
     * Implementation of training algorithm is placed in separately here due to 3d-party dependencies:
     * <https://github.com/Auron-X/GOTURN_Training_Toolkit>
     * GOTURN architecture goturn.prototxt and trained model goturn.caffemodel are accessible on opencv_extra GitHub repository.
