Open to faculty members and students of Keio University only.
No admission fee, Pre-registration not required

Summary of lecture:

Most of the pictures we see nowadays (press, fashion, politics, social networks) usually come from digital cameras. Those images can easily be created but also altered and manipulated with more and more sophisticated image editing software. Digital image forensics is an emerging research field that attempt to detect these image falsifications and restore trust towards digital imagery, with obvious applications in the press, justice and police investigations.
During this talk, I give an overview of a large set of digital image forensics methods to detect image forgeries. These techniques can take advantage of the image compression format. Some others focus on the image consistency on noise, color and geometrical clues. Finally, I present some counter forensics pretending to make undetectable falsifications.

Biography :

Vincent Nozick received his Ph.D. in computer sciences in 2006 from Universite Paris-Est Marne-la-Vallee, France. In 2006, he was laureate of a Lavoisier fellowship for a post-doc position in the laboratory of Prof. Hideo Saito, Keio University. Since 2008, he has been a tenured "maitre de conferences" (assistance/associate professor) at Universite Paris-Est Marne-la-Vallee, France. He served as a head master of the Imac engineering school from 2011 to 2013. He held a "delegation CNRS" position from 2016 to 2018 at the Japanese French Laboratory for Informatics (JFLI), at Keio University, NII and The University Tokyo, Japan. In addition to computer vision applications, his research interests include both digital image forensics and geometric algebra.
