Remote photoplethysmography (rPPG) enables us to capture the vital signs such as pulse rate, respiratory rate, oxygen saturation, and even heart rate variability (HRV) without any contact devises. Although the papers of rPPG mainly focus on the use of standard RGB camera, it cannot used for the cases in night or under the dim light conditions. Therefore, in this paper, we propose a novel noncontact method for monitoring HRV without visible lighting. The proposed method uses dual-band infrared videos to ensure robustness to fluctuations in illumination. The hemoglobin component is extracted via a simple projection from the dual-band pixel values in logarithmic space. We demonstrate the accurate extraction of pulse wave signals using pulse wave maps. As the results, we indicated the effectiveness of HRV monitoring in the situation under the dim light condition. © 2018 Society for Imaging Science and Technology.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
