View-dependent texture coding for transmission of virtual environment
Stefan Horbelt · 1997
: We propose a novel technique for coding of texture and three-dimensional data which takes the viewer position into account. This allows to transmit only the most visible parts of information that is needed to render a virtual scene. The rendering operation is modelled and studied using filtering and sampling theory. The technique is applied on real data and results are given for an operational encoding system. Keywords: view-dependent scalability, anisotropic filtering, DCT filtering, very low bitrate, synthetic texture coding, back-channel, computer graphics. 1 INTRODUCTION The development of digital communication has led to an astounding amount of research in the field of compression and transmission of video information. This research has developed several standards for the coding of digital video, which are now widely used. In parallel, digital networks like the Internet provide new means for exchange of visual information. This kind of network offers the ability for the user t...
