Using an algorithmic technique, researchers at MIT can now reconstruct audio that makes objects vibrate just by “reading” the video of those objects vibrating. The data — like this a houseplant’s “minute” movements generated by someone playing “Mary Has a Little Lamb” at it — can be gathered and translated into audio signals, which then can be played back. Behold, muffled, creepy “Mary Little Lamb,” via houseplant. The method can be used to extract intelligible speech from video of a bag of potato chips filmed from 15 feet away through soundproof glass. In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant. The researchers will present their findings in a paper at this year’s Siggraph, the premier computer graphics conference. https://youtube/watch?v=FKXOucXB4a8#t=12
