Eulerian video magnification- Amazing use of video to monitor pulse and respiration
Video of pulse sample skip to 1:30 (color), and 3:19 (motion). Video of respiratory rate 3:39
Detail of pulse changes:
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.
