Multidimensional signal processing for visual and multimedia services

各种类型的图像形式的视觉数据仍然是消费者和专业人士最丰富的信息来源之一。近年来，随着通信服务和网络以及支持图像的设备的进步，基于图像的服务已经变得普遍，特别是那些利用互联网和无线网络的服务。然而，这些服务中的许多仍然提供质量、真实感和响应性不足的服务，特别是对于非常高分辨率的图像和三维环境。该研究计划的总体目标是开展新的多维信号处理技术的研究，这些技术可应用于增强型视觉通信和多媒体系统的开发。本课程将探讨三个主题：多维信号处理理论；彩色图像处理和渲染；以及全方位和高分辨率图像和视频处理。要研究的具体主题包括：不同类型的图像和视频的新的更有效的多维表示，包括全向图像；彩色图像处理的新方法，用于数码相机和彩色显示器等；用于沉浸式远程呈现应用的立体全向成像系统的设计；以及视频信号上转换的方法，如HDTV到超级HDTV的转换。在所有情况下，目标都是发展基本的新理论，导致比目前的方法更高质量和/或更有效的实施。培训的学生将获得图像和视频处理方面的高价值技能，包括软件开发。成像在现代世界的所有领域都变得无处不在，包括商业、消费电子和个人通信。因此，这些部门的所有行业都对具有成像及相关领域技能的人才有着强烈的需求。

Visual data, in the form of diverse types of imagery, remains one of the richest sources of information for both consumers and professionals. With advances in communications services and networks, and image-enabled devices, image-based services have become pervasive in recent years, especially those making use of the Internet and wireless networks. However, many of these services still offer inadequate quality, realism and responsiveness, especially for very high-resolution imagery and three-dimensional environments. The general objective of this research program is to carry out research on new multidimensional signal processing techniques that can be applied to the development of enhanced visual communications and multimedia systems. Three main themes will be pursued: multidimensional signal processing theory; color image processing and rendering; and omnidirectional and high-resolution image and video processing. The specific topics to be researched include: new more efficient multidimensional representations for different types of images and videos, including omnidirectional images; new methods for color image processing, for applications in digital cameras and color displays, among others; design of stereoscopic omnidirectional imaging systems for immersive telepresence applications; and finally, methods for video signal upconversion, such as HDTV to super HDTV conversion. In all cases, the goal is to develop fundamental new theories that lead to higher quality and/or more efficient implementation than current methods. The students trained will acquire high-value skills in image and video processing, including software development. Imaging is becoming ubiquitous in the modern world in all sectors, including business, consumer electronics and personal communications. Thus, all industries in these sectors have a strong need for personnel with skills in imaging and related fields.
