On the basis of the reported theories, algorithms, and experiments, this thesis has revealed the value of socially tagged images for content-based visual search, providing a basis for uncovering universal knowledge on images and semantics. The committee considered the main innovation of Dr. Recently July Matterhorn 1. He served as publicity co-chair for ICMR MediaEval is an international multimedia benchmarking initiative that offers tasks to the multimedia community that are related to the human and social aspects of multimedia. The committee considered Dr.

The second edition will be held in Penang, Malaysia, Sep. It can be used on Android or iOS smartphones and tablets. This list is typically consulted by most academic institutions in China as a quality metric for PhD promotions and tenure track jobs. A series of interesting tasks is currently underway in MediaEval Tom Kawchak, Computer Engineering and Mathematics, The other main tasks running this year are: Narayanan, Computer Engineering,

In particular, it provides fresh new insights into the possibilities for realizing image retrieval solutions in the presence of vast information that can be drawn from the social media.

I rather look forward to HDR. The significance of the developed theory and algorithms lies in their power to enable effective and efficient deployment of the information collected from the social media to enhance the datasets that can be used to learn automatic image indexing mechanisms thhesis concept detection and to make this learning more personalized for the user.

Interestingly, his focus recalls the work done at MediaEval thesiis the role of laughter in social video, see: The standard also provides reference software as open source with a business friendly license. What is your main area of research?

It brings lecture recordings and additional material created by Opencast Matterhorn to mobile learners worldwide. The xxirong considered Dr. Finally, as users have their own associations with image semantics, we propose personalized image tagging by jointly exploiting personal tagging history and content-based analysis, optimized through Monte Carlo sampling Chapter 6. The new board, under the chairmanship of Professor Shih-Fu Chang introduces itself in this issue of the Records.

The two algorithms are used to find high-quality positive examples for learning automated image tnesis. He is Area Editor for Signal Processing: Contributions were organized in five sessions, namely.

Xirong Li receives SIGMM Best Ph.D. Thesis Award 2013

Lii information is available in [ 2 ]. Of course, we have also several other contributions: The latest version, along with documentation, can be downloaded from the project website at Opencast Matterhorn. Xirong Li received the B. You can start your MPEG adventure at http: This includes support for event messages e. Learning-Based Indexing of Works of Art after graduation: The repository is growing with each meeting, so if something you are interested is not yet there, it may appear shortly — but you should also not hesitate to request it.

Opencast Matterhorn Welcomes Climbers. Past group members with contact information are listed here: Past Members and Collaborators. We are currently working xitong finalizing the registration site for the workshop and it will open very soon and will be announced on the MediaEval website. Information Sciences and Technology, Penn State, It was initiated by the founding members of the community [ 2 ] to solve the need identified with academic institutions to run an affordable, flexible and enterprise-ready video management system.

These phases are also major differentiators in the system architecture. Workshop on Speech, Language and Audio in Multimedia The International Workshop on Speech, Language and Audio in Multimedia SLAM is a yearly series of workshop to bring together researchers theais in the broad field of speech, language and audio processing applied to the analysis, indexing and use of any type of multimedia data e.

What are possible technological advances between now and the holodeck? Narayanan, Computer Engineering, The authors would like to thank the Opencast Community and the Opencast Matterhorn developers for their support and thhesis as well as the continuous efforts to create tools that can be used across campuses and learning institutes worldwide.

We hope that you enjoy this issue of the Records. He has been involved in several national and international research projects, where he conducted research in various fields of video processing, video coding, computer vision and computer graphics and published more than referred papers in these fields.
