Abstract
In recent years, so-called 3-dimensional video has received a significant attention both in research and in industry. Applications are ranging from special effects in feature films to the analysis of sports events. 3D video is concerned with the computation of virtual camera positions or fly-throughs of a scene given multiple, conventional 2D video streams. The high-quality synthesis of such view-independent video representations poses a variety of technical challenges including acquisition, reconstruction, processing, compression, and rendering. In this talk I will outline the development of research in this area done at ETH over the past years. I will discuss various concepts for passive and active acquisition of 3D video using combinations of multiple cameras and projectors. Furthermore, I will address the issue of representation and processing of the massive amount data arising from such multiple video streams. I will highlight the underlying technical concepts and algorithms that draw upon methods both from graphics and from vision. Finally I will demonstrate some commercial applications targeting at virtual replays for sports broadcasts.
