“One of the main insights of the paper is that domain-specific methods are able to yield bigger improvements than more general approaches. This is an important lesson that will have ramifications for other domains.”

Who would have thought...

So it's a general lesson about domain-specific methods, not a domain-specific lesson?

Did we really need this project to discover the value of heuristics?

I think other domains don't really need to be told - the value of generative models is well known, from Bayesian inference (ABC) to deep learning. This is a nice little application of the idea of using a generative model to do inference but the lesson is not new.

The rule of being specific also matches this title. This is for very very limited artificial video game footage and a database of known 3D scenes from the same. Hardly what I expected.

They are using recorded footage and depth maps from a FIFA game to 're-match' new footage with depth.

While they are using "artificial video game footage," as the basis for their process, they are applying it to real soccer game footage. Limited, yes, but quite clever in its simplicity. (Obviously, in general, the idea of using simulated data as a training set for supervised machine learning isn't new, but who would have thought that an off-the-shelf videogame would be realistic enough to be used to reconstruct 3d scenes from actual soccer footage.)

Thanks for the clarification, I somehow misread.

I played with Samsung's 2D to 3D conversion in 2011 and found it to be surprisingly good at live action content.

While looking into their conversion technology I found a mention of TriDef. They have several OEM downloads indicating they provide the 2D to 3D conversion for some Samsung, HP, LG, and Phillips displays.

Stergen[0] did this few years back(had a working system in 2010 IIRC). Their results are very good for soccer, and good for basketball and american football(all for live broadcast footage, in realtime). Unfortunately (for them) nobody watch 3D television anymore.

Just watched the youtube clip on my 3dtv and the results were terrible. The people are on the same plane as the grass. They aren't standing up out of the grass. I'm convinced it's junk like this that has made 3dtv so unpopular. I show people 3d gaming or proper 3d movies on my 3dtv and they had no idea the experience they were missing out on. More than one person has told me they were now going to go buy a 3dtv (good luck finding a passive 3d interlaced tv nowadays). I have the Vizio E3D320VX. Took me 2 months to find the one I ended up with. I paid about twice as much as a regular tv for it.

3D has always been a gimmick back since the first stereo photographs were produced. I don't see any reason that will change.

Same with binaural sound. Mono was good enough for Miles Davis, it should be good enough for everyone.

No, seriously, your comment is useless. OP said he likes it for video games & you don't even address that.
