Formational Parameters and Adaptive Prototype Instantiation for MPEG-4 Compliant Gesture Synthesis
نویسندگان
چکیده
This paper introduces Gesture Engine, an animation system that synthesizes human gesturing behaviors from augmented conversation transcripts using a database of highlevel gesture definitions. An abstract scripting language to specify hand-arm gestures is introduced that incorporates knowledge from sign language research, psycholinguistics, and traditional keyframe animation. A new planning algorithm instantiates and adjusts gestures according to communicative context and temporal constraints obtained from a speech synthesizer. The system animates an MPEG-4 compliant skeleton using Body Animation Parameters.

Gesture Synthesis from Sign Language Notation Using Mpeg-4 Humanoid Animation Parameters and Inverse Kinematics
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...

This paper presents a new Web tool for converting text to Sign Language notation and corresponding VRML animation sequences for H-anim compliant avatars. The tool can be used both as a sign language dictionary as well as a text to sign language translator. It is based on a Sign Language dictionary written in the well-known SignWriting system. More specifically, the entries of the dictionary are...
متن کامل3D Body Animation and Coding within a MPEG-4 Compliant Framework
Referring to the new functionality of video access and coding, the work presented here lies within the scope of MPEG-4 activities related to Face and Body Animation (FBA). Specifically, we show how the new MPEG-4 standard offers an appropriate framework for virtual actor animation, gesture synthesis and compression/transmission. The targeted multimedia service concerns a low bit rate video-phon...
