Quite preplxed, is it not the same thing shown in the movie Eagle eye !!!
MIT, Microsoft and Adobe researchers recently took a video of a room from 15 feet away through a pane of soundproof glass. Even though they obviously couldn’t hear, they were able to tell exactly what was said inside the room. Their secret? A vibrating bag of potato chips caught on film.
“When sound hits an object, it causes the object to vibrate,” lead paper author Abe Davis said in a release. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there.”
The team created an algorithm that can translate those tiny vibrations back into audio, allowing them to extract intelligible speech from objects. The researchers successfully pulled sound from videos of tinfoil, water in a glass and a plant.
Their work could be useful to determine the composition of different types of objects. As Davis put it, “different…
