متن کاملSign Language Synthesis for the Mobile Environments
This paper describes the synthesis of sign-language animation for mobile environments. Sign language is synthesized by using either the motion-capture or motion-primitive method. An editing system can add facial expressions, mouth shapes and gestures to the sign-language CG animation. Sign-language animation is displayed on PDA screens to inform the user of his/her mobile environment.
متن کاملAnalysis and Synthesis of Facial Expressions by Feature-Points Tracking and Deformable Model
Face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. In this paper we develop a facial expressions analysis and synthesis system. The analysis part of the system is based on the facial features extracted from facial feature points (FFP) in frontal image sequences. Selected facial feature poi...
متن کاملSynthesis of virtual reality animation from sign language notation using MPEG-4 body animation parameters
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 Sign Writing 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 Si...
