Image Processing for Broadcast and Video Production : Proceedings of the European Workshop on Combined Real and Synthetic Image Processing for Broadcast and Video Production, Hamburg, 23–24 November 1994

Recent developments in computer visualisation mean that it is now possible to combine computer-generated image sequences with real video, in real time, for broadcast quality production. This will not only revolutionise the broadcast industry, by making electronic film sets possible for example, but also has important implications for related fields such as virtual reality, multi-media, industrial vision, and medical image processing. This volume contains papers from the European Workshop on Combined Real and Synthetic Image Processing for Broadcast and Video Production, held in Hamburg, 23-24 November 1994. The papers cover three main aspects of research: hardware, image analysis, and image synthesis, and include several key contributions from the EU RACE II supported MONA LISA (MOdelling NAturaL Images for Synthesis and Animation) project. The resulting volume gives a comprehensive overview of this important area of research, and will be of interest to practitioners, researchers, and postgraduate students.
