Contactless Blood Pressure Estimation using infrared video from facial and hand regions

This study investigates the potential of using low-cost infrared cameras for non-contact monitoring of blood pressure (BP) in humans. Previous research has shown that robust contactless BP monitoring using RGB cameras is possible. In this study, the Eulerian Video Magnification (EVM) technique is employed to enhance minor variations in skin pixel intensity in the forehead and palm regions captured by an infrared camera. The primary focus of this study is to explore the possibility of using infrared cameras for contactless BP monitoring under low-light or night-time conditions. Results show that the proposed approach has surpassed the stringent accuracy standards set forth by the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI) protocol.
