A Java-based MPEG-4 Facial Animation Player

چکیده
IST project INTERFACE aims at improving user interaction with web-based applications by following a “man in the machine” metaphor. Computer-animated characters will be used, acting as virtual consultants, clerks, or teachers. Parameter-based facial animation is now a mature technology, and has also been included in the MPEG4 standard. To make this technology available on the Web, the authors have developed a Java port of the FAE facial animation software created at DIST. While showing an acceptable performance reduction with respect to the original FAE, the Java version is considerably more flexible: it can be used either as a stand-alone Java applet and as part of more complex, multi-user online worlds. This paper describes JFAE architecture, which is based on the Java3D object-oriented graphics library. The results of several tests that compare performances of the Java and native code versions are also presented.

Facial motion cloning
We propose a method for automatically copying facial motion from one 3D face model to another, while preserving the compliance of the motion to the MPEG-4 FBA standard. Despite the enormous progress in the field of Facial Animation, producing a new animatable face from scratch is still a tremendous task for an artist. Although many methods exist to animate a face automatically based on procedur...
متن کاملVirtual Emotion to Expression: A Comprehensive Dynamic Emotion Model to Facial Expression Generation using the MPEG-4 Standard
In this paper we present a framework for generating dynamic facial expressions synchronized with speech, rendered using a tridimensional realistic face. Dynamic facial expressions are those temporal-based facial expressions semantically related with emotions, speech and affective inputs that can modify a facial animation behavior. The framework is composed by an emotion model for speech virtual...

Digital Interactive Storytelling (DIS) is a relatively novel area of computer entertainment which aims at investigating interactive applications capable of generating consistent, emergent and rich stories. To provide new solutions for DIS, we have proposed a novel multi-agent DIS framework, DIEGESIS, which includes agents' coordination and new planning and replanning solutions for DIS. A natura...
متن کاملMPEG-4 facial animation technology: survey, implementation, and results
The emerging MPEG-4 standard specifies an objectbased audiovisual representation framework, integrating both natural and synthetic content. Tools supporting three-dimensional facial animation will be standardized for the first time. To support facial animation decoders with different degrees of complexity, MPEG-4 uses a profiling strategy, which foresees the specification of object types, profi...
متن کاملFeature Point Based Mesh Deformation Applied to MPEG-4 Facial Animation
Robustness and speed are primary considerations when developing deformation methodologies for animatable mesh objects. The goal of this paper is to present such a robust and fast geometric mesh deformation algorithm. The algorithm is feature points based i.e. it can be applied to enable the animation of various mesh objects defined by the placement of their feature points. As a specific applica...
