QuoteComputer vision researchers have uncovered a world of visual signals hiding in our midst, including subtle motions that betray what's being said and faint images of what's around a corner.
QuoteThis summer, they demonstrated that they can film a houseplant and then reconstruct a three-dimensional image of the rest of the room from the disparate shadows cast by the plant's leaves. Or they can turn the leaves into a "visual microphone," magnifying their vibrations to listen to what's being said.
