Physiological signals, including heart rate (HR), heart rate variability (HRV), and respiratory frequency (RF) are important indicators of our health, which are usually measured in clinical examinations. Traditional physiological signal measurement often involves contact sensors, which may be inconvenient or cause discomfort in long-term monitoring sessions. Recently, there were studies exploring remote HR measurement from facial videos, and many methods have been proposed. This talk first introduces this new emerging research topic and recent methods in heart rate measuring from remote face video analysis. Then the application to atrial fibrillation (AF) with the video-extracted HRV features is presented, together with a new Oulu Bio-Face (OBF) database as a benchmark set.
