Due to the advent of optical prospective motion
correction techniques, it is becoming increasingly
common to place MR-compatible video cameras inside the
scanner bore during imaging. In this work, we show that
video data of the skin can be used to obtain both
cardiac and respiratory signals from the subject without
requiring a marker or any other form of physical
contact.
