Struct opencv::video::TrackerNano

pub struct TrackerNano { /* private fields */ }

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).
