Face and 2-D mesh animation in MPEG-4
2000
Signal processing. Image communication
Preserved Fulltext
We discuss both specification and compression of face animation and 2D-mesh animation in MPEG-4. Face animation allows to animate a proprietary face model or a face model downloaded to the decoder. ...
This paper presents an overview of some of the synthetic visual objects supported by MPEG-4 version-1, namely animated faces and animated arbitrary 2-D uniform and Delaunay meshes. ...
Tekalp His current research interests are video coding, computer vision, 3D modeling, face animation, coarticulation of acoustic and visual speech, computer-human interfaces, and speech synthesis. ...
