Research on 3D Facial Expression Simulation Technology

Abstract

In order to generate realistic facial animation, this paper uses depth learning object detection technology to detect the three wrinkles of human face, and then the adaptive threshold algorithm is used to extract the wrinkle curves, finally applies realistic wrinkle animation to the virtual face model. In the aspect of expression animation simulation, based on MPEG-4 standard, a database of expression parameters covering six major expressions has been established, which divide the human face into four main animation units and other auxiliary animation units. According to the displacement of animation unit between neutral expression and other expressions, the facial bone points of virtual model are driven to move, thus realizing realistic facial expression animation.
