Figure 1: An example of using our Eulerian Video Magnification framework for visualizing the human pulse. (a) Four frames from the
original video sequence (face). (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. The complete sequence is available in the supplemental video.
