Facial animation techniques

This paper describes a methodology for constructing and animating realistic models of human faces. We present three physically-based techniques. The first, an adaptive meshing method, is able to create nonuniform facial meshes from high resolution data acquired by scanning a subject with a laser range sensor. The face model includes synthetic facial tissue and muscle actuators based on anatomical and biomechanical considerations. From video sequences of a subject performing expressive articulations, the third method estimates facial muscle contractions and inputs these as dynamic control parameters to the model in order to yield realistic, performance-controlled facial animation.

Techniques for Realistic Facial Modeling and Animation | SpringerLink

Hello animators! Dana Boadway-Masson, veteran mentor and animator, shows us how to approach facial expressions in your animation. We are in for a real treat today as she gives us insight in what to look out for, workflow techniques, and how to make your facial performances more dynamic. Get ready take your facial animation to the next level! Read on, get inspired, and enjoy! And that is truly where we achieve the illusion of life, when we can make the audience believe that our character is thinking and reacting in a spontaneous manner. Successful performances combine clarity and subtlety to communicate the thought process of the character to the audience.

Facial Animation 101

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.

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. The paper will summarize and describe the related theories, strength and weaknesses for each technique.
