Fake videos? Computer program generates eerily realistic fake images

Don’t believe everything you see.

We are all aware of the ongoing battle against fake news, which frequently includes coined text and forged images, but a new computer program can manipulate video in a bewildering and compelling way.

The program can modify the video in such a way that the person on the screen reflects the movements and expressions of someone in a different video.

Scheduled to be unveiled at a computer animation festival in Vancouver, the software can also alter head and torso poses, eye movements and background details to create more compelling fakes. , according to Science News.

These video fakes are “surprisingly realistic,” Adam Finkelstein, a computer scientist at Princeton University not involved in the work, told Science News.

The program could have practical uses, such as producing dubbed movies where the actors’ lip movements match a voiceover, but it could also take the fake news problem to a whole new level.

Science News reports that the algorithm begins by scanning two different videos frame by frame, following 66 “facial cues” to map a person’s features, expression, head tilt and line of sight.

For example, in the example posted above, which shows former President Barack Obama and Russian President Vladimir Putin, the program would distort Putin’s image to adopt the head pose and facial expression of Obama.

Technology can even change shadows, change someone’s hair, or adjust shoulder height.

The final result ? A strange video of Putin making a convincing imitation of Obama’s exact movements and expressions.
