Title: | eNightTrack : restraint-free depth-camera-based surveillance and alarm system for fall prevention using deep learning tracking | Authors: | Mao, YJ Tam, AYC Shea, QTK Zheng, YP Cheung, JCW |
Issue Date: | Oct-2023 | Source: | Algorithms, Oct. 2023, v. 16, no. 10, 477 | Abstract: | Falls are a major problem in hospitals, and physical or chemical restraints are commonly used to "protect" patients in hospitals and service users in hostels, especially elderly patients with dementia. However, physical and chemical restraints may be unethical, detrimental to mental health and associated with negative side effects. Building upon our previous development of the wandering behavior monitoring system "eNightLog", we aimed to develop a non-contract restraint-free multi-depth camera system, "eNightTrack", by incorporating a deep learning tracking algorithm to identify and notify about fall risks. Our system evaluated 20 scenarios, with a total of 307 video fragments, and consisted of four steps: data preparation, instance segmentation with customized YOLOv8 model, head tracking with MOT (Multi-Object Tracking) techniques, and alarm identification. Our system demonstrated a sensitivity of 96.8% with 5 missed warnings out of 154 cases. The eNightTrack system was robust to the interference of medical staff conducting clinical care in the region, as well as different bed heights. Future research should take in more information to improve accuracy while ensuring lower computational costs to enable real-time applications. | Keywords: | Computer vision Deep learning Object tracking Patient monitor Bed exiting Fall Hospital ward |
