Fricking AMAZING: Eulerian Video Magnification for Revealing Subtle Changes in the World

From four frames of video, highlight someone's pulse. (Obviously, only one of many apps.) via +Nat Torkington's always fabulous "Four Short Links" column on

This right after I saw a pop piece about a laser being used to detect from your skin color whether you'd been eating your vegetables..

Eulerian Video Magnification

An example of using our Eulerian Video Magnification framework for visualizing the human pulse. (a) Four frames from the original video sequence. (b) The same four frames with the subject's pulse …
