| Lecturer Profile |
WU Hongren received his PhD in electrical and computer engineering from the University of Wollongong, N.S.W. Australia, in 1990. Dr. Wu was on academic staff of Chisholm Institute of Technology and then Monash University, Melbourne, Australia from April 1990 to January 2005, last as an Associate Professor in Digital Systems. Since February 2005, Dr. Wu has been with Royal Melbourne Institute of Technology, Australia, as Professor of Visual Communications Engineering, serving concurrently from 2005 to 2010 as Discipline Head of Computer and Network Engineering in School of Electrical and Computer Engineering. Professor Wu’s research interests include fast DSP (digital signal processing) algorithms, digital picture compression and quality assessment, video processing and enhancement, embedded DSP systems and their industrial applications. |
| Lecture Abstract |
This talk examines the state-of-the-art in the aforementioned three key areas closely related to perceptual 3D video coding and highlights an agonising impasse in a much needed paradigm shift for video coding design based on Shannon’s entropy and rate-distortion theories from a bitrate driven to a visual quality driven design approach. By examining visual distortions/artefacts induced by standard video coders, it raises the need for further quantitative evaluation of inter‐view masking and facilitation effects, visibility thresholds at JND level and the supra-threshold region, and disparity measurements of luminance-, texture-, chroma-, and/or frequency-contents-mismatch between the two views for either 3D video quality/ experience assessment or visual quality regulated 3DV coding design. It provides insights into a comprehensive mathematical formulation and illustration of a theoretical framework for perceptual quality regulated encoding of 3D video in terms of just noticeable differences and techniques applicable to various coding components of the framework. |
