Seeing Beyond the Naked Eye
Eulerian magnification can see your pulse in video
A new video processing technique from a team at MIT analyzes subtle changes on the pixel level, and then magnifies those changes by adjusting the video’s time scale. As a result, invisible changes can be magnified … even a person’s pulse as it drives blood through their face!
The hope is that automated video systems (like hospital observations or security cameras) can use tools like this to decipher tiny changes. The possibilites seem endless: surveillance, lie detection, satellite imagery, animated GIFs …
