    "abstract": "This paper discusses applications for the use of depth metadata acquired with a production system that is under development in the EU IST-MetaVision project. The aim of the project is to develop a camera and production system to capture, store, and distribute program material that meets the demands of both the film and television industries. The key idea for cost-effective processing is to acquire and store metadata in addition to essence data (image material) such as camera and scene parameters. Available depth-sensing techniques are reviewed in order to identify suitable methods. At the current stage of technology no single technique covers all practical production situations, so several complementary techniques and a framework to integrate them are proposed. The requirements for representation and sensing of depth information are discussed for specific applications, and initial results are presented. Applications include the creation of special effects in post-production, optimized image coding, and (interactive) stereo viewing 3-D television (3-DTV).",

From 1991 to 2000 he worked as a research scientist at the University of Hannover, where he was involved in several industrial, national, and international projects in industrial image processing and 3-D scene reconstruction. Grau joined the BBC R&D in April 2000, as a senior research engineer on the virtual production team. His main interests are 3-D surface reconstruction for applications in high-end animations and interactive programs.",

One of his first projects involved the development of phase correlation for motion estimation. He received a Ph.D. for this work as an external student with the University of Essex in 1990. The algorithm was incorporated in several commercial products, leading to a Queen's Award for Technology in 1998. He is the (co)inventor of 18 patents and has published many papers on image processing. Thomas is currently the project manager responsible for development of virtual production technology.",
