Abstract:

Modern computer graphics technologies brought realism in computer-generated characters, making them achieve truly natural appearance. Besides traditional virtual reality applications such as avatars, games, or cinema, these synthetic characters may be used to generate realistic fakes, which may lead to improper use of technology. This fact raises the demand for advanced tools able to discriminate real and artificial human faces in digital media. In this seminar, the state of the art on discrimination between computer generated and natural faces will be revised, discussing also recent approaches which propose solutions based on advanced computer vision technologies allowing the  extraction of physiological measurements from video sequences. The analysis of such physiological signals and/or facial dynamic information can also be exploited to tackle the strictly connected problem of face anti-spoofing.
