In some cases the image is so convincing it may override what you think you know. "These people can move around, look to the side, and still the image is mapped onto the generic face model and back really well." It has made "tremendous progress," says Slusallek. That's why it looks so convincing, because in some sense it is the original face of that original actor or person."Īnd the technology keeps getting better and faster. "The original face is just being animated in different ways. "That is essentially what is being used to create these deepfakes," says Slusallek. "There's a generic model of a face that people have developed over time, and AI can be used in the form of deep learning networks to look at an image of a face and map it to a 3D model of that generic face," says Philipp Slusallek, a professor of computer graphics at Saarland University in south-western Germany and scientific director at the German Research Center for Artificial Intelligence.īasically, the AI superimposes one face onto another, including gestures, and speech and eye motion.

How bad do you have to be to be banned from Pornhub and Reddit?!" And here's how you know how bad this content is: Pornhub and Reddit said they didn't want it on their platforms. "So the next thing people did was this awful, awful thing of taking famous people and not famous people and creating involuntary pornography. "The first we saw of this was people screwing around putting Nicholas Cage's face in all sorts of movies, and I think most people would say 'That's pretty harmless,' but you could see the trend," says Farid. The fakes were so good, technically speaking, that if you weren't paying proper attention (and who would be?), you may well have thought Watson had gone from feminist to freak - and you would have believed it. #ICYMI: Some dastardly individuals used a freely available software that deploys an artificial intelligence (AI) to paste the faces of known female actors like Emma Watson onto those of porn stars. Carrie Fischer will reportedly appear in "Star Wars: Episode IX" posthumously, but without CGI effects Image: picture alliance / Take the phenomenon of "deepfake celebrity porn" videos, which popped up on the social media platform Reddit at the end of 2017. A fake video can be incredibly compelling because it's a moving image. The movie industry uses computer-generated imagery (CGI) to bring dead actors back to life, like Peter Cushing (Grand Moff Tarkin) in Star Wars "Rogue One," models are routinely photoshopped in advertising, and we've made an art of auto-tuning the vocals of professional singers who can't sing.īut video manipulation is a special case. Computer technology has been used to manipulate images, video and audio for legitimate purposes too - although some examples may be ethically ambiguous. "States do it, bad actors do it, criminals do it and hoaxers do it."Īnd it's not only dictators and demons. "Look back through Hitler, Stalin, Mao or Castro, all of these people manipulated photos in an effort to change history," says Hany Farid, a professor of computer science at Dartmouth College in the United States. We've been manipulating the way we want to see the world - and how we want others to see us in it - for almost as long as humans have been able to paint or take photos.
