- Is it possible to reconstruct sound from high-speed video images?
Part of this video was sponsored by LastPass: bit.ly/2SmRQkk
Special thanks to Dr. Abe Davis for revisiting his research with me: abedavis.com
This video was based on research by Dr. Abe Davis and colleagues. I found out about this work years ago and was fascinated by the way he was able to capture vibration information in image-only video. I always imagined the motions of objects would be visible as when recording a tuning fork in slow motion - so deriving sound from high speed images seemed a feasible task. But the reality is much more difficult.
Sound vibrations only cause objects to wiggle by about a micrometer. This is much smaller than a pixel, so the algorithm must understand the characteristics of the image. A move in one direction should cause some pixels to lighten slightly, while others darken - and this behavior is correlated along the edges of the image. So noise can be reduced because it's random over the image and there are enough places to sample that you can get it to cancel out.
Something I'm wondering now is - would it be possible to capture sound in a single image? I'm thinking it would have to be an image of a large object or space because the wavelengths of typical sounds are quite long. Maybe a high frequency sound could be imaged in a suitable medium...

Genuine laugh from an original joke I appreciated that
I absolutely loved the moment where he realized why he couldn't hear it. You get that a lot when programming and it always hits you like a train and gets you excited.
That kind of reaction without any vocal exclamations usually leaves the surrounding people baffled: "WHAT? WHAT? DID YOU FIND ANYTHING? WHAT IS IT?" :D
Oh boy I get that a lot. It's like "Wai-… I think… if I… no… no wait… how abou-…" and you're like simulating the entire universe in your mind while from your mouth you can't even say a single word.
@@sabikikasuko6636
Exactly. You can see how it should go, so you check every single part along the path and you will inevitably find the problem, assuming you are capable fixing the problem (aka, you know what to look for).

Have you heard the phrase " there is logic in this madness "?
well this i not one of those cases.
in the industry i work in, we use high speed cameras to record the displacement to figure out the frequency something is vibrating at, so that we can damp it if needed. we use super bright lights on the object in order to reduce the noise at the frame rates required. makes total sense that you can pull music from it! nice!

no knowledge is inherently evil
man the absolute insane significance in intelligence and spying that he just casually dropped at the end
Decades ago I read about an eavesdropping rig that bounced a laser off a window and could detect the variations in the reflected beams to capture every spoken word inside the room. Curtains, blinds and such did not stop the glass from acting as a speaker diaphragm. Its only distance limit was the spread of the laser beam- the beam spot on the glass had to be some percentage smaller than the sheet of glass you were aiming it at.
@@christopherpardell4418 there's a youtube tutorial for that
@@christopherpardell4418 wouldn't some types of window severely degrade the quality. Frosted glass would diffuse the beam and provide a lot of noise, and I'd imagine that different types of glass would require unique calibration.
I'm unfamiliar with this, so I'd be grateful if you could provide me with a jumping off point
@@expertoflizardcorrugation3967 I don’t know a lot about this- but my understanding of how laser ranging works is that a frosted window would scatter the light, which would only make it easier to pick up the unique wavelength in more than one location. For example, soldiers using a laser target designator fire a laser at something they want a bomb to hit… the laser light reflects off in all sorts of directions, and the sensor on the bomb can detect this light and home in on the object reflecting the light. Because the laser light is a coherent beam from the designator- the bomb can’t see that beam and so won’t steer towards the soldiers, but it Can see the light that is scattered off of the object because it has been scattered off in all directions. The bomb can see the laser light bouncing off the object from anywhere.
Similarly, a laser eavesdropper would simply be looking for the interference pattern in the reflected light versus the initial beam to detect how the window pane is vibrating from sound inside the room. I would think the best way to interdict such a system would be to coat the windows in something like Fanta Black that absorbs ALL light that hots it… but then, it wouldn’t be much of a window, would it?

This reminds me of when people in 2008 heard Édouard-Léon Scott de Martinville's unintentional 1860 sound recording for the first time in history by scanning the blackened paper he etched the soundwaves onto. I like seeing historic moments like these taking place and the senses of awe and accomplishment people feel when they make these discoveries.
unintentional? I take it you mean he did not know of a way to play the sounds back
the fact that as cameras improve each year means that by each year this would be easier to do to the point where AI can possibly be able to do it with us not even needing a microphone.

I remember first hearing about this concept about 20 years ago or so. It's amazing to see how far we've come.
Still trying to work the bugs out of having a laptop that can produce a sound for BT speaker, but not produce the sound from its preformance speakers... 🤔
Very interesting video. Sure, the sound signal is subject to Nyquist sampling constraints. Each observation from the image is effectively the output from a planar microphone. Consider taking observations from >1 spot from the images. Observing multiple vibrations of the planar microphone across the surfaces will effectively multiply the sampling frequency by the number of observations. The wave pressure will be smeared in time across the image at the speed of sound. It might be possible to reconstruct some directional information as well by noting the progress of the wavefronts across the scene. Microphones arranged across multiple planes (e.g. x-y, y-z, x-z), will observe different signals. It might be possible to improve direction-finding accuracy by modulating the orientation of the planar microphones (like a dog cocking its ears). Since you know the medium (sound in air at some temperature), you are also getting information about how observed signals vary over time..
But is that how they could read the emotions of a Bobble-head in motion?

"This saves your valuable Brain space..." was mentioned during the promotion of last pass. This statement made me wonder if saving valuable brain space helps the brain in remembering more or not memorizing things makes your memory/brain weaker ... Another topic to explore :)
In my life, some of my ignorance has caused me to be able to do things that had not actually been done by my "heros". Not paying attention to some things can be an advantage. This must be true of attention span in some eccentric way. Look up Kim Peek. Industrialism largely ignores this, I think. Not just saving "space", but liberating orientation within and without dimension.
I really loved it. The guy looked like they would show programmers in films. There was a full set of ups and downs and rising tensions, with a satisfying climax. And when he realised what happened, it was just amazing, it's something I can relate to, when solving a problem and the answer suddenly comes up.

Amazing. I've truly have learned something cool. So obvious (sound wave causing objects to vibrate), yet so unexpected.
Super cool I had seen the crumble chips bag experiment before and I always wanted to try it. I think they used a rolling shutter at the time which would give a much higher sampling frequency if you extract the horizontal movements. Maybe 2 cameras at 90 degrees angle could give a nice result too!!

nah an onion article
If was from buzzfeed it was read:
Angry white man participating in male patriarchy science yells at bag of chips oppressing female diversity in workforce
😂😂
Imagine the mother walking in like “what the hell are you doing??” GET OUT MOM I AM DOING A SCIENCE!!! Then it just cuts away to her tearfully calling to get her son institutionalized coz he’s lost his mind.
Liberal media sucks.
"Man shouts meow to egg"
It's been common spook tech for decades, to operate LASER bugs that detect sound inside rooms, especially via detection of window glass vibrations. That's in effect like using a high speed camera and doppler sensing of motion, but narrowly focused and with high resolution.
Since LASER wavelength is faster than any normal or even scientific ultra-fast camera frame rate, the challenge then is sorting desired audio from noise, particularly if done from a few kilometers away, or using a window also exposed to outdoor urban noise.
I liked the moment of the deep rhythm sound on my stereo at 9:17
Nice video!
This is some CIA stuff. >:O
I'm sure they already have it
@@niqhtt if they don't, they do now.
You mean your tin foil hat reveals your inner secrets by just looking at it? 😱
Reminds me of the movie "Eagle Eye" The Visual Microphone
Search it up
Yes and no. It only works with high resolution, high framerate video of ideal materials, so I doubt it's more effective than using a laser microphone unless you happen to have silent video from some lab experiment.
I can recover screams from images of someone stepped on a lego brick.
Nailed it!
🤣🤣🤣🤣
There's a brazilian fiction book I read as a kid (don't remember the name, gotta search in my parents' shelf), back in around 2005 IIRC, which actually has some plot around using a device that can recognize writing machine keystrokes by sound. Just found it interesting coincidence you mentioned that idea in the lastpass ad.
Some Contact moment right there! Great video! Love these garage experiments (technically apartment)....
High FPS required?
Call up the SlowMoGuys, they can help with that.
MazeFrame But then the file size of the video may crash the computer...
We are limited by our technology I guess
@@cmarley314 That's why we need a quantum computer. Hope we can buy them next year - I need to upgrade my computer too.
@@spadaacca quantum computers aren't necessarily better at handling every application than current computers

"can you get sound from pictures"
person with schizophrenia: why is that even a question?
I always wondered if it was possible to recover a 3d image of an object in the past if you could determine the amount of light that bounced off and had hit a certain area of the room.
