中文摘要
摘要0313056斯温德尔赫斯特,阿诺德杨百翰大学当前的视听记录,通信和回放提供了一个单一的,二维的世界,因为它随着时间的推移而变化的观点。人类生活在一个“四维”的世界里,在这个世界里,他们按照自己的意志(随着时间的推移在三维空间中)移动,从任何角度体验世界。传感器、计算机和网络技术的进步使得采用多个摄像头和麦克风以及复杂的处理算法的新系统成为可能,从而提供前所未有的沉浸式录制和观看能力。足够的传感、网络和计算能力实际上已经实现了这一愿景;实现它的关键差距是缺乏必要的信号处理理论和算法。本研究将开发新的信号处理技术,用于从多个声学和视频传感器在空间和时间的任意位置重建音频和视频记录,通过扩展自适应波束形成的最新研究,非平稳信号的多传感器信号处理,以及多维信号表示的基本新进展。实际的四维视听记录,传输和回放,或“远程现实”,将被证明与低成本,传统的传感器连接到网络计算机,从而证实了所提出的方法和应用的实用性。
英文摘要
Abstract0313056Swindlehurst, ArnoldBrigham Young UniversityCurrent audiovisual recording, communication, and playback provides a single, two-dimensional perspectiveof the world as it varies through time. Humans live in a \four-dimensional" world, in which they move about(in 3-D space over time) at their own volition to experience the world from any perspective. Advances insensor, computer, and networking technologies now make possible new systems that employ multiple cam-eras and microphones together with sophisticated processing algorithms to deliver unprecedented immersiverecording and viewing capabilities. Sufficient sensing, networking, and computing power to practically ad-dress this vision already exists; the critical gap in achieving it is the lack of the necessary signal processingtheory and algorithms.This research will develop new signal processing techniques for reconstruction of the audio and visualrecording at an arbitrary location in space and time from multiple acoustic and video sensors, by extendingrecent research in adaptive beamforming, multisensor signal processing of non-stationary signals, and fun-damental new advances in multi-dimensional signal representation. Practical four-dimensional audiovisualrecording, transmission, and playback, or \remote reality", will be demonstrated with low-cost, conven-tional sensors attached to networked computers, thus confirming the practicality of the proposed methodsand applications.
