The generation of facial animation data can be approached in different ways: 1.) marker-based motion capture on points or marks on the face of a performer, 2.) markerless motion capture techniques using different type of cameras, 3.) audio-driven techniques, and 4.) keyframe animation.
The Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. [1] It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978. [2]
The facial animation is then outputted to the game engine either as bone transformation or morph target frame by frame. To create a realistic animation curve, the program recognizes 42 phonemes and tries to take co-articulation rules into account. It also tries to create head movement, blinks, and eyebrow raises from emphasis points in the ...
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 ...
Computer facial animation is a highly complex field where models typically include a very large number of animation variables. [61] Historically speaking, the first SIGGRAPH tutorials on State of the art in Facial Animation in 1989 and 1990 proved to be a turning point in the field by bringing together and consolidating multiple research ...
Skibidi Toilet is a machinima web series created by Alexey Gerasimov and released through YouTube videos and shorts on his channel DaFuq!?Boom!.Produced using Source Filmmaker, the series follows a war between human-headed toilets and humanoid characters with electronic devices for heads.
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 1972, in a project partially financed by DARPA, Parke made the first 3D animation of a representation of a human face, his wife's face. This animation used a wireframe geometry overlaid with Gouraud shading that produces approximate renderings of curved surfaces. The technique was invented by Parke's Utah colleague Henri Gouraud.
