The article is a little light on detail so here is what I found via Google. They wrote what looks to be an interesting paper: Non-contact, automated cardiac pulse measurements using video imaging and blind source separation: http://www.opticsinfobase.org/abstract.cfm?uri=oe-18-10-10762 http://www.opticsinfobase.org/abstract.cfm?uri=oe-18-10-1076... Looks like they use an ordinary macbook webcam/matlab/opencv/software (to reduce noise) and are able to extract the pulse rate from it. I wonder what the implication would be for video in general. Could we determine the heart rate of someone off a news feed, presidential address, or movie??
