A new system takes a still image of a person and an audio clip, and uses them to create a doctored video of the person speaking the audio. The results are still a little rough around the edges, but the software could soon make realistically fake videos only a single click away. At the moment, these systems focus on changing the shape of the mouth, but it's only a matter of time before they can also change facial expressions and posture, says Alex Champandard, co-founder of creative.ai, "Pretty soon we will have trouble distinguishing between real and fake video," says Champandard. Given enough time, experts can already create fake videos that are virtually indistinguishable from genuine ones.
There's a lot of exciting work going on at the interface between art and artificial intelligence at the moment. In the last year we've been both amazed and horrified by Google's DeepDream, which can turn any image into a psychedelic lizard-dog freak-out, and we've loved the results of DeepForger, which uses a similar process but instead turns pictures into more traditional works of art.
