Tutorial Title / Organizers
- Context-Aware Multimedia Retrieval and Delivery
Organizers: Yi Yu, SuhuaTang, Jialie Shen
- Depth-Based 3D Video Techniques and Systems
Organizers: Ce Zhu, University of Electronic Science and Technology of China
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.
Yi Yu graduated from the Ph.D. course in Information and Computer Science, Nara Women’s University. Currently she works at School of Computing in National University of Singapore. Her research covers a diverse set of topics including large-scale multimedia information processing, social media analysis, and physical analytics. She was in the top winners (out of 29 teams) awarded by ACM SIGSPATIAL GIS Cup 2013, received a best paper award from IEEE ISM 2012. She is a co-organizer of 1st International Workshop on Internet-Scale Multimedia Management co-located with ACM Multimedia 2014.
SuhuaTang received the B.S. degree in electronic engineering and the Ph.D. degree in information and communication engineering from the University of Science and Technology of China. Currently, he is an assistant professor with the Graduate School of Informatics and Engineering, The University of Electro-Communications, Japan, and is a Guest Researcher with Advanced Telecommunications Research Institute International, Japan. His research interests include context-aware multimedia communication, cross-layer design, and inter-vehicle communications. He was in the top winners awarded by ACM SIGSPATIAL GIS Cup 2013. 16 of his patents have been granted in Japan.
Jialie Shen is an Assistant Professor in Information Systems, School of Information Systems, Singapore Management University, Singapore. He received his PhD in Computer Science from the University of New South Wales (UNSW), Australia in the area of large-scale media retrieval and database access methods. Dr. Shen's main research interests include information retrieval, multimedia systems and economic-aware media analysis. His recent work has been published or is forthcoming in leading journals and international conferences including ACM SIGIR, ACM Multimedia, ACM SIGMOD, CVPR, ICDE, WWW, IEEE Transactions on Circuits and Systems for Video Technology (IEEE TCSVT), IEEE Transactions on Multimedia (IEEE TMM), IEEE Transactions on Image Processing (IEEE TIP), ACM Multimedia Systems Journal, ACM Transactions on Internet Technology (ACM TOIT) and ACM Transactions on Information Systems (ACM TOIS). Besides being chair, PC member, reviewer and guest editor for several leading information systems journals and conferences, he is an associate editor of International Journal of Image and Graphics (IJIG) and area editor of Electronic Commerce Research and Applications (ECRA).
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.
Ce ZHU is currently with the school of Electronic Engineering, University of Electronic Science and Technology of China, China, as a full professor. 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.
Dr. Zhu serves on the editorial boards of seven international journals, including as an Associate Editor of IEEE Transactions on Circuits and Systems for Video Technology, IEEE Transactions on Broadcasting, IEEE Signal Processing Letters, Editor of IEEE Communications Surveys and Tutorials, Area Editor of Signal Processing: Image Communication (Elsevier), Associate Editor of Multidimensional Systems and Signal Processing (Springer), and Editorial Board Member of Multimedia Tools and Applications (Springer).
