This year, the researchers are demonstrating a new tool that leverages AI tricks to make actors look older or younger, minus the weeks of work usually needed to perfect those kinds of shots.

Using neural networks and machine learning to age or de-age a person has already been tried, and while the results are convincing enough when applied to still images, they hadn’t produce photorealistic results on moving video, with temporal artifacts that appear and disappear from frame to frame, and the person’s appearance occasionally becoming unrecognizable as the altered video plays. To make an age-altering AI tool that was ready for the demands of Hollywood and flexible enough to work on moving footage or shots where an actor isn’t always looking directly at the camera, Disney’s researchers, as detailed in a recently published paper, first created a database of thousands of randomly generated synthetic faces. Existing machine learning aging tools were then used to age and de-age these thousands of non-existent test subjects, and those results were then used to train a new neural network called FRAN (face re-aging network).
