Deepfakes
The Vox-adv-cpk model gained mainstream popularity through its use in creating and "living portraits." It allows users to take a single photograph of a person—ranging from a historical figure to a personal relative—and animate it so they appear to be speaking, blinking, or laughing. Because it is pre-trained on thousands of real human faces, it can replicate subtle micro-expressions with surprising accuracy. Impact and Ethics vox-adv-cpk
- Keypoint Detection: The model extracts self-supervised keypoints from a driving video (e.g., a person talking).
- Motion Estimation: Using a dense motion network, it predicts how each pixel in the source image should move to mimic the driving video’s expressions and head poses.
- Occlusion Mask: Since the driving video’s head may turn, revealing unseen parts of the face, the model generates an occlusion mask to in-paint missing regions.
- Generator: Finally, the generator synthesizes new frames, warping the source image and filling gaps.
