About this event

Abstract: In this talk we will address the research issues on 4D facial expression synthesis and analysis. The main purpose is to generate realistic and "valid" dynamic facial expressions. As human beings are very sensitive to any subtle changes on facial movements, it is critical to make sure the facial movements on 3D face are realistic. We solve this problem using local geometric encoding methods to map expressions from real human beings. We would like to synthesize 4D facial expression information that conveys some messages to the viewer without the use of actor performances. We will discuss how to make sure that the message intended by the dynamic 3D facial expression is actually perceived as such.
