Transcript

Dear Fellow Scholars, this is Two Minute Papers with Károly Zsolnai-Fehér. We talked about a technique by the name Face2Face back in 2016, approximately 300 videos ago. It was able to take a video of us and transfer our gestures to a target subject. With techniques like this, it’s now easier and cheaper than ever to create these deepfake videos of ... Read More

Questions & Answers

Q: What is FaceForensics++ and how does it improve upon the previous FaceForensics technique?

FaceForensics++ is a research paper that introduces an improved dataset and a detector neural network for detecting DeepFake videos. It builds upon the previous FaceForensics technique by offering more valuable insights and better detection capabilities.

Q: How effective is hiding deepfake artifacts behind compression artifacts?
