The system is based on a robust offline face tracking stage which trains the system with different facial expressions. The matched sequences are used to build a person-specific linear face model that is subsequently used for online face tracking and expression transfer. Audio-driven techniques are particularly well fitted for speech animation.
A tadpole person [1] [2] [3] or headfooter [4] [5] is a simplistic representation of a human being as a figure without a torso, with arms and legs attached to the head. Tadpole people appear in young children's drawings before they learn to draw torsos and move on to more realistic depictions such as stick figures .
Figure drawing by Leonardo da Vinci. A figure drawing is a drawing of the human form in any of its various shapes and postures, using any of the drawing media. The term can also refer to the act of producing such a drawing. The degree of representation may range from highly detailed, anatomically correct renderings to loose and expressive sketches.
The additional constraints of the face also allow more opportunities for using models and rules. Facial expression capture is similar to facial motion capture. It is a process of using visual or mechanical means to manipulate computer generated characters with input from human faces, or to recognize emotions from a user.
This drawing style has also migrated into anime, as many manga are adapted into television shows and films and some of the well-known animation studios are founded by manga artists. In manga, the emphasis is often placed on line over form, and the storytelling and panel placement differ from those in Western comics.
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 .
ASCII art of a fish. ASCII art is a graphic design technique that uses computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1963 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII).
Facial expression is used in sign languages to convey specific meanings. In American Sign Language (ASL), for instance, raised eyebrows combined with a slightly forward head tilt to indicate that what is being signed is a yes–no question. Lowered eyebrows are used for wh-word questions.
