3DTV: Technical challenges for realistic experiences

In recent years, various multimedia services have become available and the demand for three-dimensional television (3DTV) is growing rapidly. Since 3DTV is considered as the next generation broadcasting service that can deliver realistic and immersive experiences, a number of advanced 3D video technologies have been studied. In this tutorial lecture, we are going to discuss the current activities for 3DTV research and development. After reviewing the main components of the 3DTV system, we are going to cover several challenging technical issues: representation of 3D scenes, acquisition of 3D video contents, illumination compensation and color correction, camera calibration and image rectification, depth map modeling and enhancement, 3-D warping and depth map refinement, coding of multi-view video and depth map, hole filling for occluded objects, and virtual view synthesis.
