Cardiocam: Contact-free physiological measurements using video imaging.

The option of monitoring a patient's physiological signals via a remote, contact-free approach is important for advancing telemedicine and improving both the access and delivery of primary healthcare. I led the development of a method for measuring multiple physiological parameters (including heart rate, respiration rate and heart rate variability) using a basic webcam. In addition, we demonstrated that this approach can be extended to perform concurrent measurements of multiple persons.
