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 signal amplified. (c) A vertical scan line from the input (top) and output (bottom) videos plotted over time shows how our method amplifies the periodic color variation. In the input sequence the signal is imperceptible, but in the magnified sequence the variation is clear.


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.

  1. Hello! I am a nut at programming and obviously also at running things, but can you tell me how to run the example so that I will be able to follow the result of the video? I have followed the readme file in matlab, and it seems like it succeeded in doing what it was supposed to do. But I cannot see it – so in case what I’ve done so far is correct, is it then possible to make the video appear after it has been manupulated by the Eulerian Video Magnification?
