Techniques for Realistic Facial Modeling and Animation | SpringerLink
Generating facial animation has always been a challenge towards the graphical visualization area. Numerous efforts had been carried out in order to achieve high realism in facial animation. This paper surveys techniques applied in facial animation targeting towards realistic facial animation. We discuss the facial modeling techniques from different viewpoints; related geometric-based manipulation that can be further categorized into interpolations, parameterization, muscle-based and pseudo—muscle-based model and facial animation techniques involving speech-driven, image-based and data-captured.
Realistic Facial Expression of Virtual Human Based on Color, Sweat, and Tears Effects
Rendering Techniques pp Cite as. Rendering realistic faces and facial expressions requires good models for the reflectance of skin and the motion of the face. Because we build a complete model that includes geometry and bidirectional reflectance, the face can be rendered under any illumination and viewing conditions.
Computer facial animation is primarily an area of computer graphics that encapsulates methods and techniques for generating and animating images or models of a character face. The character can be a human, a humanoid, an animal, a fantasy creature or character, etc. Due to its subject and output type, it is also related to many other scientific and artistic fields from psychology to traditional animation. The importance of human faces in verbal and non-verbal communication and advances in computer graphics hardware and software have caused considerable scientific, technological, and artistic interests in computer facial animation.
