Study Notes
- Train a model to disentangle identity from expression and modify/swap encoding before decoding.
- An issue arises in determining which part of the embedding controls which attribute.
- Adding additional encoding (e.g., AU, LANDMARK, embedding) before decoding helps refine the process.
- However, there is a problem where the face shape leaks during the process.
- Converting intermediate representation to that of the target before generating the final output is an effective strategy.
- Creating a composite input from several representations and refining it with another network like pix2pix is a common approach.
- Challenges in creating deepfakes include issues related to generalization, paired training, identity leakage, occlusions, and ensuring temporal coherence.
