What it does

Deepfake tools can copy face movement or appearance, so they must be used carefully.

Landmark: A body point • Synthesis: Creating something new

How it works

  • Find face landmarks like eyes and mouth.
  • Track how the face moves.
  • Create a changed face image or video.

Uses and applications

  • Movie teams can de-age an actor for a scene.
  • Video apps can make face effects.
  • News and schools need tools to spot fake videos because they can be used to lie.

In short

Deepfakes can be used to spread convincing lies, so their output needs careful checking.

Related methods

  • GANs: One family of models used to create synthetic faces.
  • CycleGAN: Translates images between styles, a related technique.
  • Diffusion: Newer generators that can also produce realistic media.
