Quality-of-visual-experience: perceptual assessment, compression and enhancement

点击翻译按钮获取中文摘要

Recent years have witnessed remarkable advances in digital image/video acquisition, transmission and display technologies. These technologies aim to offer consumers with enhanced experience in consuming visual content, and are creating a vast change in novel multimedia applications. To maintain and increase the competitiveness in the rapidly growing global market, it is critical for Canadian academia and industry to maintain and enhance their leadership in advancing the research fronts and in developing cutting-edge technologies. The proposed project aims to explore the theoretical and application frontiers in quality-of-visual-experience (QoVE) research. First, we will develop novel objective QoVE assessment methodologies suited for network visual communications; Second, we will develop objective QoVE evaluation techniques for three-dimensional (3D) application environment; Third, we will develop novel compression and quality enhancement methodologies optimized for the best 2D and 3D QoVE. To achieve this goal, we will exploit a series of challenging problems - We will develop perceptual video compression methodologies by incorporating QoVE models; We will incorporate QoVE criteria into state-of-the-art sparse representation, compressed sensing, and statistical image modeling methodologies for the denoising, superresolution, and frame rate adaption of video signals; We will also investigate polyview fusion-based methods, and pre- and post-processing methods in network visual communications to further improve the visual experience of end users. The success of this project will help establish a necessary theoretical foundation and a series of general methodologies for the fast-evolving field of QoVE research, upon which advanced technologies can be built up for many practical applications in digital imaging, multimedia communication, entertainment, gaming, education and medical imaging industries. In the process of achieving our scientific and technological objectives, we will also train highly qualified personnel in related areas for Canada.
