A Lightweight Distributed Media Processing System for Uhd Service

With the rapid development of media services, it's an urgent demand that videos uploaded to the Internet need to be processed with high efficiency and high quality. We set up a flexible lightweight distributed system for media processing to address …

Two-stream recurrent convolutional neural networks for video saliency estimation

Recently, research has emphasized the need for video saliency estimation since its application covers a large domain. Traditional saliency prediction methods for video based on hand-crafted visual features lead to slow speed and ineffective results. …

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 …

Optimized nested protection for video Region of Interest with Raptor codes

Due to the best effort feature of many existing transmission channels, video streams often suffer from inevitable transmission errors. In this paper, we propose a scheme of robust video transmission based on the state-of-the-art Raptor codes, whose …

Prioritized Flow Optimization With Multi-Path and Network Coding Based Routing for Scalable Multirate Multicasting

In this paper, we study performance optimization for scalable video coding and multicast over networks. Multi-path video streaming, network coding based routing, and network flow control are jointly optimized to maximize a network utility function …

Distributed link-aware rate allocation for R-D optimal multiple video streaming over wireless networks

When multiple video streams are delivered in wireless networks, careful rate allocation is desirable to share the available bandwidth without overflowing the whole network or any individual link, as well as to maximize the total received quality …
