Ding ding ding...correct! I work in the Computer Vision field and have already seen presentations of plans to overlay ads inside video content. The example shown was your classic soap opera. The program detects suitable advertising surfaces for example a table top or a wall in a scene and then renders an advert in that location. This is then embedded in the video and tada you now no longer have to worry so much about piracy because you have adverts embedded in the pirated video in a way you can't easily cut out. The program automatically calculates the value of an ad location depending on time on screen, angle to camera etc. and gives a web based front end for buying ads from the TV company.
This could, given enough computation power in phones and cameras, allow companies to place ads in our videos and photographs based on location and orientation. Although it is hard to see why this would be better than placing huge billboars - but still I put nothing past an advertiser with enough intent.
I can guarantee you that there is not a neural-network behind this. I work in almost exactly the same field except my research is targeted at 'guessing' the pose of people in still images rather than in video (Natal not only has video, but also a 3D point cloud making this a fairly trivial problem). Given the amount of data Microsoft have gathered they will essentially be doing a nearest neighbour search using a very efficient classifier.
Neural networks are very out of fashion in Computer Vision and other AI fields at the moment and have been surpassed by devices such as Hidden Markov Models and Support Vector Machine classifiers.
From what I've read Natal is able to aquire depth information - using this I figure they would be able to distinguish the quite unique shape of a face (ie: nose, chin, eye sockets) from the generally round back of your head. Although things might screw up if you put long hair over your face I guess.
it just seems like it will have a severely limited scope. Much like speech recognition is GREAT in a very small set of circumstances, and a nuisance in most others.
I agree with you here, we've discussed how unimaginative the majority of the Wii games are going with just a 'waggle' to perform actions...I suspect with Natal game designers will end up having to put in a load of crazy gestures because there is no standard controller. Also think about things like golf/baseball/driving - I'm pretty sure all of these would feel much more immersive if you actually had an object in your hands as with the Wii.
3D motion capture is possible from one camera actually (I'm working on it for my PhD). There's only a small number of configurations a body can be put into to fill the same 2D silhouette as seen from a single camera.
Besides that the demo's shown in the GP video really only need 2D motion capture anyway, except maybe the accelerator for the driving game. But seriously, why would I want to stand/sit with my leg in an awkward position when I could just hold "A" instead? For the same reason my Wii is also collecting dust.
most people on here seem to knock twitter but as has been mentioned it is pretty much the only source for news right now. Follow updates on the #IranElection hashtag here:

For what it's worth I don't even use twitter, but it's times like this that I realise it kicks the ass of TV news for real-time coverage.
Use the scan-line technique to scan each line with a rapidly adjustable mix of red, green and blue lasers.
As long as the laser light spreads out proportional to the distance it has travelled the picture should look good wherever the laser will reach. My only worry is the battery life.
I think e-paper like this has definite uses for researchers or anyone else who needs to read, and more importantly add notes to printed text. My desk at university, and to be honest half of my house, is covered in printed academic papers and other research material. Theoretically I could read all of these on my laptop or PC but it's just so much easier to read from paper, and a break from staring at a glaring computer screen. Also I tend to highlight lots of text and add a tone of scribbled notes on each sheet which I find is easier and faster than annotating on screen.
If I could have say 3 A4 sheets of this e-paper I would be able to just a single sheet of 'paper' in each of my working locations. This would mean access to limitless pages of research, on a screen that presumably will be very similar to reading it on paper, and the ability to highlight and add notes stored electronically. The fact it's flexible I hope means it will be pretty durable and I'll be able to carry it about with me, shove it in a bag, whatever.
But really whatever happens with this technology think of the amount of paper it will save, and so trees, and so the world...everyone's a winner, except paper companies.
It infects your mind with vivid images of the interior of goatse man's anus. Apart from that not sure, as long as it doesn't affect Firefox+Ubuntu I'll be fi
I presumed the grandparent meant the German high-speed rail network when he said "the ICE". I did a bit of "inter-railing" over summer, travelling mainland Europe by train. Going from Brussels to Berlin we were booked on an ICE train which funnily enough had broken down! This led to a 5 hour coach trip to Aachen where there would be another trail. When we eventually got to Aachen station we ran onto an ICE train which was about to leave without checking if we actually had valid tickets. As Brits we thought must have entered a first class luxury coach. The seats were out of this world. Large, comfy, with pillows built into the head rest and with a decent table in a genuinely pleasant environment. We took a seat and the coasted out of the station accelerating smoothly to high speed fairly quickly, being a geek I couldn't take my eye off the digital speed readout at the end of the carriage. Simply the most perfect example of rail engineering I have ever experienced.
Beats the British rail network hands down, our cattle-class trains can't even handle a bit of snow!
It's the same in the UK I'm afraid. I'm studying for a PhD and anything that I devise is wholly owned by the university. However there is a clause in my contract saying that the university will essentially share the love if they exploit my ideas.

Please mods, wherever you are from mod parent up, do it for England! It has been known for the government to actually act on these petitions (or at least comment), and I've just added only the 70th signature. I personally can't wait to finish at university and get out of this rapidly sinking ship I call home, although to be honest most countries that have a similar culture (Europe/US) seem to all be going downhill...bugger...
Yup, along with O2 who use BeThere's main network. Although I could easily dodge anything censored by going to the Coral Cache (.nyud.net) so yet again this is pretty pointless. I agree that perhaps Wikipedia should block all access attempts from these IPs. At the moment it is only UK/. readers that probably know about this, block Wikipedia for 35% (source) of UK internet browsers and you'd likely have a media firestorm on your hands which would not stop until internet censorship had been killed (hopefully).
Munshi was arrested after police found an instruction manual on making grenades and napalm downloaded to his computer from the internet.
The guy got two years for this and also running a website selling knives and Islamic flags, so yeah reading material can get you in trouble, at least here in the UK. Who needs liberties!
There have been cases (all the links I can find at the moment point to out of date news URLs) in the UK at least where people have at least been detained for having things like the Anarchists Cookbook on their machine.
Yeah my bad, I knew I had it wrong when I looked a little closer at the image and saw giant footprints nearly filling the space between the tracks. Next time I'll read the caption before posting to/.!
I really like this image showing the rover tracks leading back to the Apollo 14 Lunar Module "Antares".
How anyone can look at this image in particular and claim the landings were faked is beyond me. It's a wonderful image, let's just hope we'll be back there soon to take more!

Do you think he's got the picture yet...never get your math wrong in a /. thread!
Your math is a 1000 out. 100TB ~= 100,000,000MB / 200MB = 500,000 frames for the movie, which does sound about right.
