This whole situation is rather nasty. There was enough of consternation going from NTSC ("never-the-same-color") to digital, with the bifurcation/trifurcation of SMPTE 240M, BT.601 and BT.709, plus the bifucation of "le

Author here -- this was shot with a single Richo Theta S on a rotating Fairburn multiplate on a selfie stick. Positioning was entirely manual, but used software to correct and compensate. There are a few vertical disparities (and a nice r

If you've ever been an executive member of a standards body like ISO, ITU or SMPTE, you'll understand where this sort of perspective comes from...

There were actually a lot of discussions about this sort of thing that lead up to the BIFS specification in Mpeg4 (Part 11). But BIFS obviously never anticipated virtual reality and the like, let alone light field or holography.

At least someone is thinking about putting a standard around all of this -- at least it's JPEG and not MPEG-LA. I found it very interesting how broadly they specified the goals here.

While the downvotes are cute, why punish giving credit where credit is due? I thought their quote was very clever, and worthy of drawing attention to. Just saying.

WOW, well-played, sir, very well played indeed. I may have to steal your snark.

> Actually looking forward to MS's UX folk cleaning up LinkedIn. Wait, what? Are you saying you want Microsoft to "Metro-ify" LinkedIn? Forget the OS, even, for a minute... Just look at what they did to Skype and Office.

What's also impressive to me is that Google's solution seems robust , meaning it does a good job in the face of outliers like lens flare, exposure changes, and the like. I see a lot of research with canned results where they opt

I'm an advocate of publishing not just the paper, but the compilable source and executable binary code and datasets used for just that reason. Science is not science if others can't reproduce the results and tweak and permute the

I would posit that a deep learning network that learns to optimize parameters for a complex algorithm outside the convolutional network itself may have immense utility outside the classification problem. Call it a marriage of classic c

There's some overlap, but what impresses me is that they're doing camera tracking (hard) in near-real-time and automatically (even harder) on an iPhone . Camera tracking is used in feature film visual FX frequently, and it'

That's assuming Zavodnik sent the requests via certified, registered mail. Zavodnik could have easily scribbled the address in unreadable gibberish and slapped a simple 1st class stamp on, in which case they would never have actually

This proposal sounds great, but seems to wave its hands furiously about right-of-way and eminent domain. I used to live in Astoria on Ditmars Blvd, and the proposed line would most certainly be going on/over thousands of private reside

This looks to me like something on the order of convertible warrants based initially on bitcoin/Ethereum, which convert to DAO tokens. DAO tokens appear to be some sort of collective ownership of "crypto assets" whatever THA

Well, I think you're on the right track. Right behind me are 30 supermicro pizzboxes (some have GPUs) that are racked but powered down and looking very lonely (but with 6 dark fibers also feeling lonely at the moment). Perhaps I&#x27
