An Elastic System Architecture for Edge Based Low Latency Interactive Video Applications

5G and edge computing have brought great changes to video industry. Interactive video is becoming an emerging application form of multimedia service, which provides attraction beyond typical scenarios like cloud gaming and remote virtual reality …

VMAF Oriented Perceptual Coding Based on Piecewise Metric Coupling

It has been recognized that videos have to be encoded in a rate-distortion optimized manner for high coding performance. Therefore, operational coding methods have been developed for conventional distortion metrics such as Sum of Squared Error (SSE). …

A VMAF Directed Perceptual Rate Distortion Optimization for Video Coding

Video Multimethod Assessment Fusion (VMAF), as a state-of-the-art learning-based objective assessment metric, has been demonstrated to achieve a stronger correlation with human visual system than others. However, combining multiple metrics by Support …

VMAF Oriented Perceptual Optimization for Video Coding

In the light of low costs and automatic assessment, objective visual quality metrics enjoy many important applications such as perceptual coding. Recently multiple metrics obtain further improvement by means of machine learning. However, due to the …

Video stabilization with L1–L2 optimization

Digital videos often suffer from undesirable camera jitters because of unstable camera motions. In this paper we present a novel video stabilization algorithm by mixed L1-L2 optimization, aiming at removing unwanted camera movements as well as …

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 …
