ACM SIGGRAPH Workshop: Truth in Images, Videos, and Graphics

Organizers: Irfan Essa, Chris Bregler, Hany Farid


One of the goals of computer graphics is to create images, scenes, and videos that appear real and indistinguishable from live-captured content. This goal is now quite achievable as images and videos can be synthesized with a level of realism such that we can’t tell if the content shown to us is just live-captured content, or some mixture of live content, with added manipulations and edits, or completely synthetic. While the ability to create such synthetic or hybrid content is a much-needed tool for entertainment and story-telling, it can also be used to distort the truth. Recently, we have witnessed a significant increase in both the number and success of manipulations in media. Modern graphics techniques are creating challenges for journalistic processes as truth can be easily manipulated and then shared widely. Tools from computer graphics and multimedia can now create images and videos that are indistinguishable from the real and are therefore very effective at manipulating the beliefs of consumers.

The goal of this inaugural workshop is to bring together researchers and practitioners in all aspects of media creation to understand the challenges as tools for manipulation are made available widely. We will discuss the tools and the issues around how these technologies impact society, and reflect on the responsibilities of both the technology creators and users of these technologies.

The format of this workshop will include invited speakers to set the stage for this conversation.


  • Videos of real people saying something they never said.
  • Detecting of Manipulation.
  • Staging is manipulation

His work has resulted in numerous awards from the National Science Foundation, Sloan Foundation, Packard Foundation, Electronic Arts, Microsoft, Google, U.S. Navy, U.S. Airforce, N.S.A, C.I.A. and other sources.He's been the executive producer of, which required building the world's largest real-time motion capture volume, and a massive multi-player motion game holding several world records in The Motion Capture Society. He has been active in the visual effects industry, for example, as the lead developer of ILM's Multitrack system that has been used in many feature film productions, including Avatar, Avengers, Noah, Star Trek, and Star Wars.

Alyosha Efros

Alexei (Alyosha) Efros joined UC Berkeley in 2013. Prior to that, he was nine years on the faculty of Carnegie Mellon University, and has also been affiliated with École Normale Supérieure/INRIA and University of Oxford. His research is in the area of computer vision and computer graphics, especially at the intersection of the two. He is particularly interested in using data-driven techniques to tackle problems where large quantities of unlabeled visual data are readily available. Efros received his PhD in 2003 from UC Berkeley. He is a recipient of CVPR Best Paper Award (2006), NSF CAREER award (2006), Sloan Fellowship (2008), Guggenheim Fellowship (2008), Okawa Grant (2008), Finmeccanica Career Development Chair (2010), SIGGRAPH Significant New Researcher Award (2010), ECCV Best Paper Honorable Mention (2010), 3 Helmholtz Test-of-Time Prizes (1999,2003,2005), and the ACM Prize in Computing (2016).
