Computer based facial expression modelling and animation is not a new endeavour. The earliest work with computer based facial representation was done in the early-1970s. The first three-dimensional facial animation was created by Parke in 1972.
Facial motion capture is the process of electronically converting the movements of a person's face into a digital database using cameras or laser scanners. This database may then be used to produce computer graphics (CG), computer animation for movies, games, or real-time avatars. Because the motion of CG characters is derived from the ...
Dozens of similar controllers are used to animate the rest of the face. An arbitrary object deformed by morphing between defined vertex positions. Morph target animation, per-vertex animation, shape interpolation, shape keys, or blend shapes [1] is a method of 3D computer animation used together with techniques such as skeletal animation. In a ...
FACS coding is also used extensively in computer animation, in particular for computer facial animation, with facial expressions being expressed as vector graphics of AUs. [24] FACS vectors are used as weights for blend shapes corresponding to each AU, with the resulting face mesh then being used to render the finished face. [25]
Facial Animation This is the process of animating facial animations, lip-syncing, and animating phoneme blend-shapes (shapes that the face morphs into) Autodesk Maya, Blender, Autodesk 3DS Max In Pixar's 'Turning Red', animators took influence from anime style facial expressions to inform their animation.

A facial expression database is a collection of images or video clips with facial expressions of a range of emotions. Well-annotated ( emotion -tagged) media content of facial behavior is essential for training, testing, and validation of algorithms for the development of expression recognition systems .
In 1974, he created a more complex, parametric model of a human face, demonstrating various expressions and speech synchronization. [3] Snippets of this animation, along with Ed Catmull's 1972 animation of his left hand, were used in the 1976 film Futureworld and The Walten Files.
Facial expression is the motion and positioning of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers ...
