This paper proposes a methodology to reconstruct 3D facial expressions with motion capture data. Featurepoint based facial animation provides easy control of expression usually by moving surface points using mathematical deformation. However it does not support the high quality of surface animation of the face where the feature points are not present. In this paper, we focus on animating a 3D f...

With the rapid development of facial animation and facial motion analysis, the necessity of motion capture techniques increases dramatically. However, existing motion capture devices are still very expensive and have specific limitations. In this dissertation, an accurate and inexpensive procedure for estimating 3D facial and lip motion trajectories from mirror-reflected multi-view video is pro...

Visemes are visual counterpart of phonemes. Traditionally, the speech animation of 3D synthetic faces involves extraction of visemes from input speech followed by the application of co-articulation rules to generate realistic animation. In this paper, we take a novel approach for speech animation – using visyllables, the visual counterpart of syllables. The approach results into a concatenative...

A total solution for computer facial animation is proposed. First, a well-de ned 3D head model is deformed according to several photographs with di erent views, where the 3D head model exhibits good animation features. After pose recovery, B ezier curves are used to depict the subtle contours on a face. Moreover, elastic deformation can be applied to adjust the locations of global features. We ...

This paper presents a novel approach for generating VRML animation sequences from Sign Language notation, based on MPEG-4 Face and Body Animation. Sign Language notation, in the well-known SignWriting system, is provided as input and is initially converted to SWML (Sign Writing Markup Language), an XML-based format that has recently been developed for the storage, indexing and processing of Sig...

Synchronization of speech, facial expressions and body gestures is one of the most critical problems in realistic avatar animation in virtual environments. In this paper, we address this problem by proposing a new high-level animation language to describe avatar animation. The Avatar Markup Language (AML), based on XML, encapsulates the Text to Speech, Facial Animation and Body Animation in a u...

OBJECTIVE To describe a highly quantitative facial function-measuring tool that yields accurate, objective measures of facial position in significantly less time than existing methods. METHODS Facial Assessment by Computer Evaluation (FACE) software was designed for facial analysis. Outputs report the static facial landmark positions and dynamic facial movements relevant in facial reanimation...

This chapter describes a probabilistic framework for faithful reproduction of spontaneous facial expressions on a synthetic face model in a real time interactive application. The framework consists of a coupled Bayesian network (BN) to unify the facial expression analysis and synthesis into one coherent structure. At the analysis end, we cast the facial action coding system (FACS) into a dynami...

Facial modeling and animation are increasingly receiving attention in the graphics and artificial intelligence (AI) research communities, both of which share the common goal of synthesizing believable, simulated agents. While computer graphics researchers have been primarily concerned with physical and anatomical aspects of facial movements, AI researchers and cognitive scientists have focused ...
