Video processing techniques for 3D television

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 real and immersive experiences by supporting user-friendly interactions, a number of advanced three-dimensional video technologies have been studied. Among them, multi-view video coding is the key technology for various applications including free-viewpoint video, free-viewpoint television, 3DTV, immersive teleconference, and surveillance systems. In this tutorial lecture, we are going to cover the current state-of-the-art technologies for 3D video: 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 view synthesis using homography. After defining the basic requirements for realistic 3D broadcasting services, we will cover various multi-modal immersive media processing technologies.
