Research

I am currently working in the field of Digital Video Forensics. We are interested in deteting digital video forgeries without the help of digital watermarks or signatures. The way we study this field is that, we place ourselves in the position of a forger, and ask what we need to do to make a forgery and what kind of traces we may leave behind in the tampered videos, then we develop mathematical models to characterize and detect these traces.
