We present a method that estimates high level animation parameters (muscle contractions, eye movements, eye lids opening, jaw motion and lips contractions) from a marker-less face image sequence. We use an efficient appearance-based tracker to stabilise images of upper (eyes and eyebrows) and lower (mouth) face. By using a set of stabilised images with known animation parameters, we can learn a...

In many applications, such as conversational agents, virtual reality, movies, and games, animated facial expressions of computer-generated (CG) characters are used to communicate, teach, or entertain. With an increased demand for CG characters, it is important to animate accurate, realistic facial expressions because human facial expressions communicate a wealth of information. However, realist...

In this paper we describe experiments of real-time facial animation for generation of various virtual actors using high level-actions, compatible with MPEG-4 standard specifications. An MPEG-4 compatible synthetic face and body are integrated into an interactive real-time application allowing the user-friendly control of virtual humans' facial animation and its speech in real-time. This applica...

Expressive facial animation synthesis of human like characters has had many approaches with good results. MPEG-4 standard has functioned as the basis of many of those approaches. In this paper we would like to lay out the knowledge of some of those approaches inside an ontology in order to support the modeling of emotional facial animation in virtual humans (VH). Inside this ontology we will pr...

The aim of this study is the simulation and synchronization of human facial expressions and lip motion for Turkish text using homeomorphic 3D facial models using Java Programming Language and JAVA3D API. For this purpose Turkish text is mapped to related homeomorphic 3D facial models, these models are synchronously morphed to form the animation and this animation is combined with facial express...

Inspired by kernel methods that have been used extensively in achieving efficient facial animation retargeting, this paper presents a solution to retargeting facial animation in virtual character’s face model based on the kernel projection of latent structure (KPLS) regression between semantically similar facial expressions. Specifically, a given number of corresponding semantically similar fac...

EEMML (Emotional Eye Movement Markup Language) is a scripting tool that enables authors to describe and generate emotional eye movement in virtual agents. The EEMML is capable of describing and generating both basic eye movement and emotional eye movement, including primary (joy, sadness, anger, fear, disgust and surprise) and intermediate (emotions that can be represented as the mixture of two...
