(Phys.org) —A baby lies in the crib looking motionless, a typical situation causing worry to new parents, wondering if the baby is still breathing. A video run through an algorithm designed for amplification shows the baby is indeed breathing with movements that were invisible to the naked eye. It's that special algorithm at the heart of interest in the work of a group of scientists at MIT who work on a project called motion magnification. They have said that "Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye." Their process breaks apart the visual elements of every frame of a video, reconstructed with an algorithm tool that can amplify aspects of the video.
