Before revision:  We deploy feature extraction tasks, Spatio-temporal feature tracking tasks, and signal extraction and preprocessing tasks to robot layers, edge layers, and cloud layers , respectively. We have deployed this non-contact respiratory monitoring system in the Second Affiliated Hospital of the Anhui Medical University of China . Experimental results  show that the proposed approach in this paper significantly outperforms other approaches.
After revision:  We deploy feature extraction tasks, Spatio-temporal feature tracking tasks, and signal extraction and preprocessing tasks to robot layers, edge layers, and cloud layers . We adopt this architecture to design a non-contact respiratory monitoring system in the Second Affiliated Hospital of the Anhui Medical University of China . Experimental results show that the proposed approach in this paper significantly outperforms other approaches.
