Scientists Reconstruct Video Clips From Brain Activity In Historic Experiment - Polidicks

[QUOTE=Satane;32456698]why do they have to use random youtube clips though. why not just convert whatever data they got from the brain to video? I mean they gotta have some sort of reference to find the most similar videos[/QUOTE] Yeah, that sort of confuses me too. Perhaps because it would take a lot more processing power to "decode" brain signals into moving pictures.

[QUOTE=slamex;32435960]But those dirty thoughts were meant to be for my private use only :([/QUOTE] Just think about hardcore gay buttsex and nobody will want to read your mind anyway.

[QUOTE=Satane;32456698]why do they have to use random youtube clips though. why not just convert whatever data they got from the brain to video? I mean they gotta have some sort of reference to find the most similar videos[/QUOTE] The computer doesn't know what video is. Or what a brain is, or how to understand the electrical impulses of our brain. It just knows about pieces of information. If we make a person watch a video and record what their brain does, we have two pieces of data which are linked together. If we make someone watch 5000 videos, we have a library. If we then scan their brain while they're watching something the computer doesn't know about, we can ask the computer to give us back one of the videos it knows of based on its closeness to what's being observed. The accuracy of such a system would improve if exposed to enough data just like a search engine.

Come to think of it. This will ruin the porn industry. [editline]24th September 2011[/editline] [QUOTE=Catdaemon;32456988]The computer doesn't know what video is.

They have an algorithm that allows them to match the brain activity against videos. This means that they already have the information of shape and form which means they should be able to re-create it with at least black and white.

Reminds me of silent hill

[QUOTE=TippZ;32453750]its not really the same thing is it? this is not realtime, its recreating everything with videos, whilst the "cat version" is doing it realtime...? but yea, pretty weird that they didnt try this on humans until recently[/QUOTE] It might be because our brains are much more complicated than cats so it took more to extract that 'mind' video from our brain than the cat's.

i wonder what a gay orgy looks like

[QUOTE=Baldr 2.0;32436110]Hurry up, it would be awesome to record your own dreams.[/QUOTE] I can imagine making a tv show out of my dreams.

On the subject of the image in my last post a few posts up, they did this in an episode or two of Fringe before. Amazing that some of the over the top/exagerated science from that show is actually becoming a reality. Keep an eye out for bald men observing you.

Wasn't this done in an episode of House with some girl who got a parasite through her boyfriend's dad's semen?

[URL]http://www.politedissent.com/archives/4949[/URL] I think it's "Black Hole" [quote]House convinces the team to try an experimental technology (conveniently available at that very hospital): cognitive pattern recognition. In a scene more at home on Fringe than House, the team see the image of her boyfriend playing baseball, then the universe, then an older man (“her late father” they surmise) from Abby’s brain. Unfortunately, this isn’t enough to build any sort of diagnosis[/quote]

I like how they showed Steve Martin clips.

[QUOTE=finbe;32436075]There are random words in the video for some reason like "record" I find that a bit strange.

[QUOTE=Satane;32460366]so if i'm getting this right, the brainwaves are not necessarily a picture. they're also the emotional response and the things you think of when you see something. that's why it's pretty much unique for everyone. their algorithm matches your reaction to an image to a reaction you've had to one of the thousands of youtube videos.[/QUOTE] Oh, I see. Well that sucks, that means we're actually far away from anything close to re-making what we envision in our brain. (but still being able to reconstruct fairly if not very well in 20-30 years isn't all that far-fetched) It's basically a lie detector for the brain activity.

It's amazing that the brain can actually produce video imagery. Although I don't think this is actually mind reading, it's just reading what you're seeing from your eyes. It would be seriously impressive if they could read thoughts with this however,

TOTAL RECALL REVERSED

It would be seriously impressive if they could read thoughts with this however,[/QUOTE] The problem is that thoughts aren't images, while your eyes actually send visual data (a picture or video) to your brain something like your thoughts could be represented with just "text" and I don't know about you but I don't imagine an image of words I think.

so this doesn't actually record anything , just tries to reconstruct your mental images from things that are similar?

[QUOTE=Satane;32472581]i see pictures in my head when I think of objects. table. bam. a picture of hl2 table in my head.[/QUOTE] Thinking of and imagining objects aren't the same as thoughts that are basically just words.

[QUOTE=Instant Mix;32472892]so this doesn't actually record anything , just tries to reconstruct your mental images from things that are similar?[/QUOTE] Seems it doesn't even do that. It records your brain activity (like a lie detector) for that certain video, and matches it with the other videos. As in, if you had the same kind of brain activity when seeing a frame of Duke Nukem as you had when seeing a frame of the Pink Panther, then it would use that. It has nothing to do with similarities visually in any way, only your brain activity reactions. [editline]25th September 2011[/editline] [QUOTE=CakeMaster7;32472989]Thinking of and imagining objects aren't the same as thoughts that are basically just words.[/QUOTE] Thoughts are re-creation of soundwaves. Imaginations are re-creation of wavelengths. Everything you see and hear is input to your eyes or ears. The brain process that information and makes it into sounds and visuals. Thinking and imagining does the same process, it just removes the need of ear and eyes.

It makes white people look black ha. And this would suck in the future if your girlfriend went on your PC and looked at the dream you had last week of banging every girl you see on the street.

that's piss. another badly worded article title to make it sound like something amazing.

[QUOTE=Instant Mix;32473066]that's piss. another badly worded article title to make it sound like something amazing.[/QUOTE] It's still a relative breakthrough considering where we were three years ago.

[QUOTE=Instant Mix;32473066]that's piss. another badly worded article title to make it sound like something amazing.[/QUOTE] Well, I for one think it's amazing enough to be able to record brain activity. And this is just the first step into it. It has to begin somewhere.
