Video plethysmography (also known as i-PPG) is a variant of photoplethysmography that is derived from a camera video signal.  “Imaging PPG” thus enables us to remotely measure a variety of physiological parameters via the mobile phone camera.  These parameters include: heart rate, heart rate variability, and blood oxygen saturation. We are implementing a variety of video plethysmography and face tracking methods that can run in real time on an Android phone.
