....been to extract the features in real time, we have focused our attention on recognition and analysis of only a few facial features. 3.3. Facial animation There has been extensive research done on basic facial animation and several models have been proposed. In the early models proposed by Parke [ 39 40 ], he has used a combination of digitized expressions and linear interpolation of features such as eyelids and eyebrows and rotations for jaw. Platt and Badler [ 41 ] have proposed a model that simulates points on the skin, muscle, and bone by a set of interconnected 3D network of points using ....

System Detects Recovers from Hand Occluding Face 5. 7 Video Driven Face Animation Head position and inner lip contours can be used to control synthetic head models [18] 19] 20] [21]. The head position is taken as the nostril position and controls the horizontal and vertical head model position relative to the camera model in the graphics rendering system. The head tilt is controlled by either the angle between the eye line or nostril line and the horizontal, but the eye line ....

....examples of interpolation between Marilyn Monroe and Humphrey Bogart. Fig.15 17 present a transformation from Marlyn to an extra terrestrial creature. 3. 2 A three level approach to facial animation Several models of computer generated facial expressions have been described: parametrized models [6,7] and muscle based models [8,9] Our model [10] is based on the abstraction of muscle actions (AMA) instead of the muscles themselves. To animate an actor s face, the animator must first build a certain number of facial expressions specific to her his character. The expressions are built by ....

....those who implement MPEG 4 face and body decoders to use the encoded parameter for synthesizing virtual faces and bodies. International research in computer graphics has proposed several solutions in the past decades for modeling and animating realistic 3D meshes reproducing human faces and bodies [1 3]. High level research has also been carried out for the anatomically correct modeling of bones, muscles and tissues [4 5] A lot of expertise has been consolidated also in psychological interpretation of facial expressions [6] and in bimodal acoustic visual analysis and modeling [7 8] of speech. ....

....FACS in a sophisticated computational model of the human face that we originally developed for the realistic animation of synthetic characters. Facial animation in computer graphics began with Parke s use of facial images as keyframes and his subsequent popularization of parameterized face models [22]. State of theart parameterized models can produce impressive animation using parameters associated with facial muscle structures [33] 30] Graphics researchers have devoted significant effort to parametric facial modeling but little effort to the inverse problem of extracting parameters from ....

....vision, MPEG 4 1 INTRODUCTION Computer simulation of human faces capable of reflecting mouth movements and emotional states has been a flourishing research area for a long time. A number of papers have been published, resulting in a large number of facial models and several animation systems [1, 2, 3, 4, 5, 6, 7]. The interest in this technology has been clearly shown by the inclusion of animated face features and animated 2D meshes using the MPEG 4 standard [8] Moreover, the usefulness of this technology has been proven by a set of perceptual experiments which showed that facial animation can provide ....

....of Parke [3] He used keyframing techniques and cosine interpolation to animate the face. Since each key frame must be completely specified to animate the face, simple keyframing cannot be easily used for threedimensional (3D) facial animation. Parametric systems have emerged as a result of this [4]. A parametric facial animation system defines a set of parameters for the face. These are mainly the expression parameters for different parts of the face, such as mouth and eyes and the conformation parameters that apply globally to the whole face. The major parameters for the mouth are jaw ....

....algorithm used between these positions. Only this nonlinearity and the history of the workers qualifies the approach as physically based. It might also be viewed as more properly fitting in the TA class, which we now discuss. In a seminal development [Parke, 1972, Parke, 1974, Parke, 1975, Parke, 1982, Parke, 1991] Parke modeled the facial surface as a polyhedral object composed of about 900 small surfaces arranged in 3D, joined together at the edges and smooth shaded. In his original work [Parke, 1972] key frames were used to change the shape of the face, but in subsequent work the face was ....
