Planar Bones for MPEG-4 Facial Animation
نویسندگان
چکیده
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 control structure is maintained throughout the animation, overcoming the issues of many of the current systems defined using this standard.

MPEG-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 کاملFacial 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...

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 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...
متن کاملMPEG-4 facial animation in video analysis and synthesis
MPEG-4 supports the definition, encoding, transmission, and animation of 3-D head and body models. These features can be used for a variety of different applications ranging from low bit-rate video coding to character and avatar animation. In this paper, an entire system for the analysis of facial expressions from image sequences and their synthesis is presented. New methods for the estimation ...
