• Name Non-invasive heart rate measurements from facial information
  • Duration 2011-2012

This project addresses the development of a low-cost method for non-invasive heart rate measurements. Each heart beat produces a variation in the amount of blood present in the face skin, which causes small illumination changes in it. These fluctuations cannot be seen by the human eye, but they can be sensed by a standard webcam and, applying different image and signal processing techniques, allow an accurate estimation of the heart rate. The application fields range from telemedicine, where it can be used for non-invasive low-cost patient monitoring, to liveness detection in facial recognition systems.
