Siri’s Inventors Are Building a Radical New AI That Does Anything You Ask
"Whereas Siri can only perform tasks that Apple engineers explicitly implement, this new program, they say, will be able to teach itself, giving it almost limitless capabilities."
"We present a method for converting first-person videos, for example, captured with a helmet camera during activities such as rock climbing or bicycling, into hyperlapse videos: time-lapse videos with a smoothly moving camera.
At high speed-up rates, simple frame sub-sampling coupled with existing video stabilization methods does not work, because the erratic camera shake present in first-person videos is amplified by the speed-up.
Our algorithm first reconstructs the 3D input camera path as well as dense, per-frame proxy geometries. We then optimize a novel camera path for the output video (shown in red) that is smooth and passes near the input cameras while ensuring that the virtual camera looks in directions that can be rendered well from the input."
3D Object Manipulation in a Single Photograph using Stock 3D Models
"We present a method that enables users to perform the full range of 3D manipulations, including scaling, rotation, translation, and nonrigid deformations, to an object in a photograph. As 3D manipulations often reveal parts of the object that are hidden in the original photograph, our approach uses publicly available 3D models to guide the completion of the geometry and appearance of the revealed areas of the object."
The Visual Microphone: Passive Recovery of Sound from Video
"When sound hits an object, it causes small vibrations of the object’s surface. We show how, using only high-speed video of the object, we can extract those minute vibrations and partially recover the sound that produced them, allowing us to turn everyday objects—a glass of water, a potted plant, a box of tissues, or a bag of chips—into visual microphones. We also explore how to leverage the rolling shutter in regular consumer cameras to recover audio from standard frame-rate videos."
The Kids Who Beat Autism
"In the last 18 months, two research groups have released rigorous, systematic studies, providing the best evidence yet that in fact a small but reliable subset of children really do overcome autism. The first, led by Deborah Fein, a clinical neuropsychologist who teaches at the University of Connecticut, looked at 34 young people, including B. She confirmed that all had early medical records solidly documenting autism and that they now no longer met autism’s criteria. In May, another set of researchers published a study that tracked 85 children from their autism diagnosis (at age 2) for nearly two decades and found that about 9 percent of them no longer met the criteria for the disorder.
The research by Fein and Lord doesn’t try to determine what causes autism or what exactly makes it go away — only that it sometimes disappears. There do, however, seem to be some clues, like the role of I.Q.: The children in Lord’s study who had a nonverbal I.Q. of less than 70 at age 2 all remained autistic. But among those with a nonverbal I.Q. of at least 70, one-quarter eventually became nonautistic."
