'Deepfake' AI can turn the Mona Lisa into a convincing real person


'Deepfake' AI can turn the Mona Lisa into a convincing real person

AI can now turn the Mona Lisa into a real life person with just one picture.

A paper published by a Samsung artificial intelligence lab in Russia shows the ability to convincingly turn artworks and celebrity photographs into moving images.

The technology raises the prospect of convincing "deep fakes", videos showing politicians and even people who have died saying things they never said, created just with still images of their faces.

The paintings were animated using the facial expressions of a real person, while celebrity photographs of figures such as David Beckham were turned into video using footage of them speaking on a different occasion.

The researchers, based at the Samsung AI Center in Moscow, also performed the effect on images of Marilyn Monroe and Albert Einstein, using the moving facial features of other people which was then "mapped" onto their faces, a technique known as "puppeteering".

Other models have required a large set of images in order to create a fake video, but Samsung's method can do it with just one, though the effect is more convincing if more images are used.

In the Mona Lisa example, a video published by the same team shows that the animated painting looks slightly different depending on the person used as the moving image source.  "We show that such an approach is able to learn highly realistic and personalized talking head models of new people and even portrait paintings," the authors said.

Concerns have been raised about the potential uses of such technology in the wrong hands, and the ability of the public to be able to distinguish between real videos and those which have been created in order to influence public perception of a politician.

Last year US lawmakers warned that such faked videos could be damaging to national security.  Researchers and even journalists have created convincing fake videos of figures including former US president Barack Obama and Russian President Vladimir Putin.

In one case a speech given by Mr Obama was "mapped" onto images of Mr Putin, making it look like they were his words.

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that the patient is 3,000 kilometers away,”  he said.

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke

Visualizing The Power Of The World's Supercomputers

Visualizing The Power Of The World's Supercomputers   BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM   A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is  flops , or  floating point operations per second . In this visualization,  Visual Capitalist's Marcus Lu uses  November 2021 data from  TOP500  to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used  teraflops  as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku  was completed in March 202
