Eulerian Video Magnification for Revealing Suble Changes in the World

Our goal is to reveal temporal variations in videos that are difficult     or impossible to see with the naked eye and display them in     an indicative manner. Our method, which we call Eulerian Video     Magnification, takes a standard video sequence as input, and applies     spatial decomposition, followed by temporal filtering to the     frames. The resulting signal is then amplified to reveal hidden information.     Using our method, we are able to visualize the flow     of blood as it fills the face and also to amplify and reveal small     motions. Our technique can run in real time to show phenomena   occurring at temporal frequencies selected by the user.
