When exposed to sound waves, the surface of objects in a room start vibrating. One could wonder that if we had sufficiently advanced technology, maybe the sound itself could be reconstructed from looking only at the vibration of these objects. A great technique they call "visual microphone" has been recently proposed that executes this idea with breathtaking results. _____________________ The paper "The Visual Microphone: Passive Recovery of Sound from Video" is available here: http://people.csail.mit.edu/mrub/VisualMic/ Disclaimer: I was not part of this research project, I am merely providing commentary on this work.
