No Reference Video Quality Metric for 4K-UHD Videos Based on H.264/AVC Bitstream Features
With the wide-spread use of digital videos, quality considerations have become essential, and industry demand for video quality measurement standards is rising. In this paper, we proposed a no reference video quality metric for 4K-UHD videos in the compressed domain. As video coding parameters which can reflect the degree of distortion caused by compression can be extracted in compressed domain...
متن کاملFull Reference Video Quality Model for UHD HEVC Encoded Sequences
Despite its relative robustness, subjective video quality evaluation is a time-consuming and costly process. Alternatives are required therefore to simplify visual quality estimation, particularly in the case of new video formats. This paper presents an analysis of full reference quality metrics focused on Ultra High Definition sequences, encoded with H.265/High Efficiency Video Coding. After e...
متن کاملVisual Discomfort from Camera Panning in 4K-UHD Contents
In this paper, we analyze the visual discomfort caused by camera panning in 4K UHD contents. UHD is expected to provide a sense of realness to viewers, with four times more pixels than HD. However, UHD may yield undesirable artifacts, such as the stroboscopic effect from displaying frequency and visual fatigue due to moving objects. To investigate the visual discomfort in the presence of camera...
متن کاملSubjective Analysis of Video Quality on Mobile Devices
We summarize a recent mobile video quality assessment (VQA) database that we have created which incorporates a wide variety of distortions including uniform compression and wireless packet loss, along with dynamically varying distortions that change as a user views a video on his mobile device. We evaluate a large number of objective image and video quality assessment (IQA/VQA) algorithms with ...
متن کاملAutonomic Control for Quality Collaborative Video Viewing
We present an autonomic controller for quality collaborative video viewing, which allows groups of geographically dispersed users with different network and computer resources to view a video in synchrony while optimizing the video quality experienced. The autonomic controller is used within a tool for enhancing distance learning with synchronous group review of online multimedia material. The ...
