Abstract

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.

3D电视视频处理技术

近年来，各种多媒体服务已经出现，对三维电视(3DTV)的需求迅速增长。由于3DTV被认为是下一代广播服务，可以通过支持用户友好的交互来提供真实和身临其境的体验，因此许多先进的三维视频技术已经被研究。其中，多视点视频编码是自由视点视频、自由视点电视、3d电视、沉浸式电话会议、监控系统等应用的关键技术。在本教程中，我们将介绍当前3D视频的最新技术:3D场景的表示，3D视频内容的获取，照明补偿和色彩校正，摄像机校准和图像校正，深度图建模和增强，3D扭曲和深度图细化，多视点视频和深度图编码，遮挡物体的孔填充，以及使用单应性的视图合成。在定义了真实3D广播服务的基本要求之后，我们将介绍各种多模态沉浸式媒体处理技术。
