Context-Aware Multimedia Retrieval and Delivery


Rapid advances in mobile computing and web technologies enable users to interact, create, and share online multimedia contents anytime and anywhere. Consequently, multimedia data are generated and aggregated on the Internet at a surprising speed. Its volume is too large for manual navigation that users now leverage information retrieval to find contents satisfying their interests. Users’ preferences depend on both physical context (location) and virtual context (social connection). In addition, efficient delivery of popular contents requires local caching, which also depends on the context of local user population. 

In this tutorial, we exploit contextual information as a key element to connect content sharing services and online social services, aiming at addressing personalized, localized, and socialized multimedia content discovery, recommendation and diffusion across user-generated diverse datasets. Further, we discuss fundamental components and show examples involving multimedia processing, acquisition anddescription of mobile user-generated data, location-aware social multimedia, social activities and multimedia sharing and diffusion, and present the latest advanced multimedia topics, applications, and methods based on existing novel works.

Depth-Based 3D Video Techniques and Systems


Riding on the success of 3D cinema blockbusters and the advancements in stereoscopic display technology, 3D video applications have been gathering momentum in recent years. By providing the perception of depth in addition to form, color and motion, 3D video promises to further enhance the visual experience and interactivity by vividly extending the conventional “flat” video into a third dimension. Several 3D video prototypes have been developed based on distinct techniques in 3D visualization, data format representation, and content production. Among them, stereoscopic 3D video has gained a strong momentum in consumer market, establishing itself as the first wave of 3D-TV.

Conventional multi-view video is a natural representation for stereoscopic displays, while more sophisticated 2D-plus-depth format with depth-image-based rendering (DIBR) has been attracting increasing attention from both industry and academia, as the DIBR technique helps to further advance the interactivity in 3D video systems and to significantly enhance the 3D visual experience relative to conventional stereoscopic systems. With the DIBR technique, it becomes possible to generate additional viewpoints using 3D warping techniques to adjust the perceived depth of stereoscopic videos or to provide the necessary input for auto-stereoscopic displays that do not require glasses to view the 3D scene. This functionality is also useful for free-viewpoint video (FVV), where the viewer has the freedom to move about in front of the display, and is able to perceive natural perspective changes as if looking through a window.

This tutorial aims to address the significance of depth-based 3D video processing and present a technical overview of DIBR-oriented 3D video system, with spe cific discussions on the technical challenges, recent advances and developments, e.g., content generation, view synthesis, coding and quality issues of 3D video.

He had been with the School of Electrical & Electronic Engineering, Nanyang Technological University (NTU), Singapore, for 14 years from 1998 to 2012, where he was a Research Fellow/Program Manager, Assistant Professor and then promoted to Associate Professor in 2005. Before that, he pursued postdoctoral research at Chinese University of Hong Kong in 1995, City University of Hong Kong, University of Melbourne, Australia, from 1996 to 1998. He has held visiting positions at Queen Mary, University of London (UK), and Nagoya University (Japan) supported by Tan Chin Tuan Exchange Fellowship and NUS/NTU-JSPS Scientist Exchange Program, respectively. He received the B.S. degree from Sichuan University, and the M.Eng and Ph.D. degrees from Southeast University, Nanjing, China, in 1989, 1992, and 1994, respectively, all in electronic and information engineering. His research interests include image/video coding, streaming and processing, 3D video, joint source-channel coding, visual perception and applications, and multimedia systems. Dr. Zhu has authored or co-authored over 100 publications (including 29 IEEE journal papers), which have received about 1900 citations in Google Scholar. As the lead editor he has lead-edited three books and contributed fourbook chapters. He also holds 14 patents (6 granted in US, Singapore and China, and 1 transferred). He has received best paper award and student paper award (co-authored with his student) at two international conferences (IIH-MSP 2013 and MobiMedia 2011). He has been a Principal Investigator (PI) or Co-PI for a good number of R&D projects (funded by government and industry) on image/video coding, communications and processing over years.
