It's a technique called "Diminished Reality" and for those who don't want to watch the video, the program takes the original video, reduces (diminishes) the quality, removes the artifact then increase quality and improve the result over and over.

Stream to result is 40ms.
lol mirror in the bathroom. This is very coool, though I did see a few hiccups.
Wow, that's amazing. I want to make something like that, now!
This looks amazing, and not that complicated to do. Is there a program all ready out, or will we have to wait? I might try something like this in photoshop/GIMP later... Nice find overall!
I would like to know how they manage to just go back and increase the quality back to it's original after decreasing it, though. Is that really something you can do like that?
I think maybe what it does is, copy the image somewhere safe, lower quality, remove artifact, increase quality using original image's quality, and continue doing that until it's finished. Just a guess. I want this program btw Smile

If they can, then CSI isn't a lie after all.

No, it's not really. Either they're oversimplifying for the sake of the video, or something shady is going on. Where's the scholarly paper so I can look at the science behind it?
IIRC the ability to do this is based on the fact that most images are redundant, allowing you to shrink an image, re-enlarge it, and modify it based on the lower-quality content to look nicer without a visual loss in quality.

They can do it because they have the original quality image. They can re-sample with the source, thus allowing them to get back to the original quality. They are probably using the same techniques as the GIMP plugin or photoshop feature that does a content-aware remove in still images. Not all that surprising somebody did it with video - which is just a collection of stills after all Wink (looks like photoshop does a better job, too :/ )

This is *WAY* more impressive IMO




@Kerm: ENABLE THE FULLSCREEN BUTTON!!! I HATE YOU FOR NOT ALLOWING FULLSCREEN!!! Seriously, fix that already, what the hell?
Wow, that is incredibly amazing!

Well, then they should say they're using adaptive resampling (cf. the Healing Stamp/Brush tool in GIMP and whatever its equivalent is in Photoshop) than claim some hogwash about "enhancing the quality." What are they, CSI?

Agreed.

I've told you it was before. Ever notice that every other site allows you to fullscreen an embedded video? Didya think that was voodoo magic or something?

Heck, the embed code Youtube gives you allows for fullscreen:
Quote:
<object width="640" height="390"><param name="movie" value="http://www.youtube.com/v/FgTq-AgYlTE&hl=en_US&feature=player_embedded&version=3"></param><param name="allowFullScreen" value="true"></param><param name="allowScriptAccess" value="always"></param><embed src="http://www.youtube.com/v/FgTq-AgYlTE&hl=en_US&feature=player_embedded&version=3" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="640" height="390"></embed></object>
Yeah yeah yeah, I never really noticed it enough to get past wondering why people always linked to videos with embedded fullscreen forbidden. Let's get back on-topic.

I'm not _as_ impressed, but the first time I saw it I was. I watched it again and noticed that the legs of the Baywatch Runner never changed. They look normal on his original, but when he's beefed up they look like he's been in a wheel chair for twenty years; Joe from Family Guy.

Both are great, and both have their flaws. But that 40ms turn-around, being able to keep the object removed even as the camera changes perspectives and distance, and how light weight the program seems to be is astounding.

Fix it.

True, it is much better at subtle manipulation than drastic ones, but the ability to track a marker-less person in a video? That's pretty darn impressive.

How long does Photoshop or GIMP take to remove an object from a still image 1280x720 in size? As in, is that 40ms even impressive or just par for the course? They are also essentially the 3rd people to do this, so it isn't impressive at all. Unless I'm missing something, just take each frame of the video and run it through the GIMP plugin (which is open source), you wouldn't need to do much work at all.
The reshape thing is pretty intense, though I'll be more impressed when it doesn't take bluescreening to do it.....unless that basketball shot wasn't?

I'm a little unclear on that. They seemed to be implying that it was live, and the way the background warps on the leftmost one makes me think it's not [green|blue]screened.

I'm pretty sure that was showing that it can work WITH a [color]screen, I don't think it required one. After all, they manipulated a baywatch shot.
As Kllrnohj correctly points out, the Baywatch one was definitely not bluescreened, and as I pointed out, I don't think the basketball shot was either.
