2021-10-20 Detecting Synthetic Faces by Understanding Real Faces - Shruti Agarwal
Admission: Free, General Admission, open to the public, registration required.
The creation of sophisticated fake videos has been largely relegated to Hollywood studios or state actors. Recent advances in deep learning, however, have democratized the creation of sophisticated and compelling fake images, videos, and audios. This synthetically generated media -- so-called deep fakes -- continue to capture the imagination of the computer-graphics and computer-vision communities.
At the same time, the easy access to technology that can create deep fakes of anybody saying anything continues to be of concern because of its power to disrupt democratic elections, commit small to large-scale fraud, fuel disinformation and misinformation campaigns, and create non-consensual pornography.
To contend with this growing threat, in this talk our speaker will describe a diverse set of techniques to detect state-of-the-art deep-fake videos. One set of these techniques are identity-specific, exploiting soft- and hard-biometric cues like dynamic facial motion and static facial appearance. Another set of these techniques are identity-independent, exploiting the dynamics of lip and ear motion.
