In this study, we combined physically-based modeling and parameterization to generate realistic speech animation on synthetic faces. We used physically-based modeling for muscles. Muscles are modeled as forces deforming the mesh of polygons. Parameterization technique is used for generating mouth shapes for speech animation. Each meaningful part of a text,which is a letter in our case,correspon...

Facial animation has reached a high level of photorealism. Skin is rendered with grain and translucency, wrinkles are accurate and dynamic. These recent visual improvements are not fully tested for their contribution to the perceived expressiveness of virtual characters. This paper presents a perceptual study assessing the impact of different rendering modes of expressive wrinkles on users’ per...

In this paper, we applied local warping techniques to construct a frame work of image-based morphing for facial expressions animation with low complexity. From the experience we obtained in various spatial transformations, the local warping methods are more adequate for facial expressions morphing. We utilized two transformations that can deal with local deformations: piecewise polynomial trans...

This paper describes the synthesis of sign-language animation for mobile environments. Sign language is synthesized by using either the motion-capture or motion-primitive method. An editing system can add facial expressions, mouth shapes and gestures to the sign-language CG animation. Sign-language animation is displayed on PDA screens to inform the user of his/her mobile environment.

This paper presents a hybrid method for synthesizing natural animation of facial expression with data from motion capture. The captured expression was transferred from the space of source performance to that of a 3D target face using an accurate mapping process in order to realize the reuse of motion data. The transferred animation was then applied to synthesize the expression of the target mod...

Facial animation is traditionally considered as important but tedious work for most applications, because the muscles on the face are complex and dynamically interacting. Although there are several methods proposed to ease the burden from artists to create animating faces, non of them are fast and efficient in storage. In this paper, we introduce a framework for synthesizing lips-sync facial an...

In this paper an interactive facial animation system is described The system is built on top of the facial animation system developed by Keith Waters which uses a muscle based face model We built an interactive facial animation system on top of it to produce keyframe animations of a synthetic face model The user creates keyframes interactively by either giving prede ned universal expressions to...

Direct parameterisation is among the most widely used facial animation techniques but requires complicated ways to animate face models which have complex topology. This paper develops a simple solution by introducing a PDE-based facial animation scheme. Using a PDE face model means we only needs to animate a group of boundary curves without using any other conventional surface interpolation alg...

This paper proposes a deformation technique called Planar Bones, derived from Surface-oriented Free Form Deformations, and explores its application to the context of Facial Animation. The warping method proposed uses as the control input a polygonal mesh, which is built as a triangulation of the Feature Points defined by MPEG-4. A strong correspondence between the facial geometry and this contr...

A new approach to the generation of a feature-point-driven facial animation is presented. In the proposed approach, a hypothetical face is used to control the animation of a face model. The hypothetical face is constructed by connecting some predefined facial feature points to create a net so that each facet of the net is represented by a Coon’s surface. Deformation of the face model is control...
