Special Issue on Image and Video Quality Assessment

The aim of this special issue is to provide an overview of state-of-the-art IQA/VQA methods and to address new developments towards various directions. The issue starts with an invited paper that surveys an area of great current research interest, namely NR QA. It is followed by another survey paper, which examines audiovisual QA. The next two papers each propose a novel image quality metric, one based on gradient profiles, and the other on structural similarity. They are followed by a paper on perceptual deblocking. Video quality is the topic of the last two papers, one investigating spatio-temporal interactions in VQA, and the other the impact of visual attention on VQA.

Video quality

Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically, compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impacts the user's perception of a system. For many stakeholders in video production and distribution, assurance of video quality is an important task. Video quality evaluation is performed to describe the quality of a set of video sequences under study.
