     * the Nano tracker is a super lightweight dnn-based general object tracking.
     *
     * Nano tracker is much faster and extremely lightweight due to special model structure, the whole model size is about 1.9 MB.
     * Nano tracker needs two models: one for feature extraction (backbone) and the another for localization (neckhead).
     * Model download link: https://github.com/HonglinChu/SiamTrackers/tree/master/NanoTrack/models/nanotrackv2
     * Original repo is here: https://github.com/HonglinChu/NanoTrack
