IMPACT OF VIDEO TRANSCODING ARTIFACTS ON THE SUBJECTIVE QUALITY

Touradj Ebrahimi, Francesca De Simone, Mauro Lattuada, Frédéric Dufaux, Lutz Goldmann

Video transcoding is an important step to enable interoperability between different networks, terminals, applications, and services for video communication. This paper studies the influence of typical video transcoding artifacts due to frame rate reduction ...

Error-resilient Scalable Compression based on Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian-Wolf (SW) and Wyner-Ziv (WZ). In this work, a performance analysis of image and video coding schemes based on DVC are presented, ...
