Title: Camera-Based Physiological Sensing for Fitness and Healthcare

Abstract: This tutorial will focus on the principles and techniques of camera-based contact-free physiological sensing, an area of research that has gained increasing attention due to its applications in non-intrusive health monitoring across various sectors such as fitness, healthcare, and automotive safety. The tutorial will cover methods for extracting physiological signals such as heart rate, heart rate variability, respiration rate, and blood oxygenation saturation without direct physical contact. It will address the technical challenges associated with contact-free sensing, primarily the low signal-to-noise ratio caused by subject movement. The tutorial will provide a comprehensive view of how principled and deep learning approaches can effectively manage these challenges under practical conditions to reliably extract physiological signals. The tutorial content is designed for attendees interested in the intersection of multimedia information processing and healthcare.

Biography: Chau-Wai Wong received his B.Eng. degree with first-class honors in 2008 and an M.Phil. degree in 2010, both in electronic and information engineering from The Hong Kong Polytechnic University. He completed his Ph.D. in electrical engineering at the University of Maryland, College Park, in 2017.
