Automatic 3-D Facial Fitting Technique for a Second Life Avatar

چکیده
This paper describes an automatic 3-D facial fitting technique for a Second Life avatar. It is often difficult to create an original avatar by yourself that resembles a real person. In Second Life, the combinations of systemdefined parameters deform the shape of the avatar, and we can’t control each vertex directly. It needs to encode the deformation information into many parameters. As a reference target, we make use of MRI data that scans the real face. It is stable and not affected by lighting and diffused reflection. In our experiments, we picked up 428 vertices on the base model for facial fitting. Using the iteration technique, more than 50% of vertices are just on the reference targets, and more than 85 % are within +/3mm of errors.

For Duplication Expression and Impression
Recently, research in creating friendly human interfaces has flourished. Such interfaces provide smooth communication between a computer and a human. One style is to have a virtual human, or avatar [3], [4] appear on the computer terminal. Such an entity should be able to understand and express not only linguistic information but also nonverbal information. This is similar to human-to-human com...
متن کاملExigent: An Automatic Avatar Generation System
Avatars are pervasive in video games and virtual worlds. The automatic generation of these avatar promises to reduce player effort and provide system-defined mappings between “real” (physical) player characteristics and virtual identities. We present an avatar generation system called Exigent; given a photograph of a human face, Exigent creates an avatar. Exigent leverages two recent computer v...
متن کاملVideo-Driven Creation of Virtual Avatars by Component-based Transferring of Facial Expressions
This paper proposes an efficient and economic video-driven technique that enables the instant creation of a large diversity of virtual avatars and the automatic syntheses of vivid facial animations. The proposed technique addresses the expression transferring problem which transfers a given facial expression of a source human character to the corresponding one of a synthesized avatar. In tackli...
متن کاملAutomatic construction of 3D animatable facial avatars
Rigging for facial animation is an important but time-consuming task, which generally requires experienced artists with knowledge of facial anatomy. In this paper, we investigate whether it is possible to produce a good animatable avatar automatically, given only a 3D static triangle mesh of the head. An automatic mechanism is devised for constructing multilayer animatable facial avatars for un...
متن کاملVideo-driven state-aware facial animation
It is important in computer animation to synthesize expressive facial animation for avatars from videos. Some traditional methods track a set of semantic feature points on the face to drive the avatar. However, these methods usually suffer from inaccurate detection and sparseness of the feature points and fail to obtain high-level understanding of facial expressions, leading to less expressive ...
