    Sliding Adjustment for 3D Video Representation

    This paper deals with video coding of static scenes viewed by a moving camera. We propose an automatic way to encode such video sequences using several 3D models. Contrary to prior art in model-based coding wh...

    Image-Based Multiresolution Implicit Object Modeling

    We discuss two image-based 3D modeling methods based on a multiresolution evolution of a volumetric function′s level set. In the former method, the role of the level set implosion is to fuse ("sew" and "stitch...

    Three-Dimensional Facial Adaptation for MPEG-4 Talking Heads

    This paper studies a new method for three-dimensional (3D) facial model adaptation and its integration into a text-to-speech (TTS) system. The 3D facial adaptation requires a set of two orthogonal views of the...
