MIT researchers developed software that highlights differences between successive frames of video that are usually too subtle or quick to catch. "So, for instance, the software makes it possible to actually “see” someone’s pulse, as the skin reddens and pales with the flow of blood (video stills above), and it can exaggerate tiny motions, making visible the vibrations of individual guitar strings or the breathing of a swaddled infant in a neonatal intensive care unit." "Researchers amplify variations in video, making the invisible visible"
