“Hit me,” says Morpheus. “If you can.” Neo adopts a martial arts fighting pose, then launches a furious flurry at his mentor, flailing at him with high-speed strikes. Morpheus blocks every attempted attack effortlessly. The scene is, of course, the training sequence from 1999’s The Matrix, a movie that blew minds at the time with its combination of artificial intelligence-focused storyline and cutting-edge computer graphics.
More than 20 years later, the scene is being used as part of a Facebook demo to show me some of the company’s groundbreaking A.I. image recognition technology. On the screen, the scene plays out as normal. Almost. While Morpheus and the background are exactly the same, the 2D footage of Keanu Reeves has been transformed into a 3D model. Although this particular “pose estimation” demo is pre-rendered, Andrea Vedaldi, one of Facebook’s A.I. experts when it comes to computer vision and machine learning, said that such transformations can be rendered in real time.
That means Facebook’s A.I. algorithms can watch a regular video and, as it is playing, figure out how to turn it into a fully 3D scene, frame by frame. The Matrix is a particularly impressive version of this because the exquisitely choreographed kung fu-style maneuvers are difficult for even a human to process, let alone a machine to extrapolate. It’s not perfect at it, but it’s pretty darn good.
“This is a very, very challenging video because it shows you … acrobatic poses,” Vedaldi told Digital Trends, with almost a hint of apology creeping into his voice. “[It’s not] what you would typically see in a user application. This is done for fun just to demonstrate the capabilities of the system.”
Faced with a simpler task — say, turning a video of your kid’s soccer practice into wireframe models or doing the same thing with a still holiday snap — Facebook’s algorithms are considerably more adept. And they’re getting way better all the time.
This might seem a strange piece of research for Facebook to focus on. Better news feed algorithms? Sure. New ways of suggesting brands or content you could be interested in interacting with? Certainly. But turning 2D images into 3D ones? This doesn’t immediately seem like the kind of research you’d expect a social media giant to be investing. But it is — even if there’s no immediate plan to turn this into a user-facing feature on
For the past seven years, Facebook has been working to establish itself as a leading presence in the field of artificial intelligence. In 2013, Yann LeCun, one of the world’s foremost authorities on deep learning, took a job at
Figuring out how to better understand photos is a big focus for the company. Since 2017, Facebook has used artificial neural networks to auto-tag people in photos even when they are not manually labeled by users. Since then, the social media giant’s image recognition technology has gotten increasingly sophisticated.
Ironically, one of the most recent ways this was highlighted to users was when Facebook experienced problems. In July 2019, a temporary outage stopped many photos from showing up on
Facebook’s now going further than playing “Where’s Waldo” with 2D images. As a slide that accompanies Facebook’s The Matrix demo makes abundantly clear: “We wish to understand everything in 3D, on a single glance.” It’s not just people, either. “We would like to really get A.I. to be able to understand the world just as we do,” Vedaldi said.
That means showing it a picture of an airplane and having it be able to recognize it as a plane, understand its shape in 3D space, and predict how it will move. Same thing for a chair. Or a bird. Or a car. Or a person doing yoga.
The rationale for this totally makes sense. No, this demo’s not going to pop up in a Facebook feature next week, but training an A.I. to better understand the world through the images that it sees is clearly of interest to Facebook’s overall business model. In
Training an A.I. to better understand the world through the images that it sees is clearly of interest to Facebook’s overall business model.
As one of the main ways that people communicate in social media, understanding what goes on in those images is immensely valuable — in all sorts of ways — to Facebook’s mission statement. Being able to understand and interact with images on a three-dimensional plane will also allow Facebook to thrive in new technologies like augmented reality. Imagine an AR app that turns your classic 2D
“The direction of our research here is pretty consistent with the company priorities,” Natalia Neverova, research lead at FAIR in Paris, told Digital Trends. “We would expect that at least a large chunk of our research eventually would be used for products. But I cannot tell specific timelines or applications.”
