The amplification process is called Eulerian Video Magnification, and is the brainchild of a team of scientists at the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory.
The team originally developed the program to monitor neonatal babies without making physical contact.
But they quickly learned that the algorithm can be applied to other videos to reveal changes imperceptible to the naked eye.
Prof. William T. Freeman, a leader on the team, imagines its use in search and rescue, so that rescuers could tell from a distance if someone trapped on a ledge, say, is still breathing.
