Deep Blind Video Quality Assessment for User Generated Videos

As short video industry grows up, quality assessment of user generated videos has become a hot issue. Existing no reference video quality assessment methods are not suitable for this type of application scenario since they are aimed at synthetic …

Quality of Experience Evaluation for Streaming Video Using CGNN

One of the principal contradictions these days in the field of video i s lying between the booming demand for evaluating the streaming video quality and the low precision of the Quality of Experience prediction results. In this paper, we propose …

Rate control model for high dynamic range video

This paper describes a luminance based rate control (RC) model for high dynamic range (HDR) video. A novel mathematical relationship between luminance and bit allocation of a coding tree unit (CTU) is presented. By adjusting the existing RC algorithm …

Review of ITU-T parametric models for compressed video quality estimation

This paper presents a review of parametric models for video quality estimation standardized in the past few years. The focus of this paper is the estimation of quality degradation caused by the compression artifacts. The models introduced in the …

Saliency based rate control scheme for high efficiency video coding

Rate control scheme plays a vital role in the circumstances of region-of-interest (ROI) based video coding, aiming to allocate a higher bit rate to the ROI while setting a relative lower bit rate ratio in non-ROI to maintain the total bit rate close …

No-reference video quality assessment on mobile devices

The explosive growth of video applications and services on mobile devices has made it important to assess video quality. In this paper, we propose a no-reference video quality assessment method for mobile videos. Based on the analysis on common …
