Introduction to the best papers of ACM multimedia 2009
Changsheng Xu, Eckehard Steinbach, Abdulmotaleb El Saddik, Michelle Zhou
Article No.: 12
DOI: 10.1145/1823746.1830482

Visual query suggestion: Towards capturing user intent in internet image search
Zheng-Jun Zha, Linjun Yang, Tao Mei, Meng Wang, Zengfu Wang, Tat-Seng Chua, Xian-Sheng Hua
Article No.: 13
DOI: 10.1145/1823746.1823747

Query suggestion is an effective approach to bridge the Intention Gap between the users' search intents and queries. Most existing search engines are able to automatically suggest a list of textual query terms based on users' current query...

Audio-visual atoms for generic video concept classification
Wei Jiang, Courtenay Cotton, Shih-Fu Chang, Dan Ellis, Alexander C. Loui
Article No.: 14
DOI: 10.1145/1823746.1823748

We investigate the challenging issue of joint audio-visual analysis of generic videos targeting at concept detection. We extract a novel local representation, Audio-Visual Atom (AVA), which is defined as a region track associated with regional...

Looking at near-duplicate videos from a human-centric perspective
Rodrigo De Oliveira, Mauro Cherubini, Nuria Oliver
Article No.: 15
DOI: 10.1145/1823746.1823749

Popular content in video sharing websites (e.g., YouTube) is usually replicated via identical copies or near-duplicates. These duplicates are usually studied because they pose a threat to site owners in terms of wasted disk space, or privacy...

LiveSky: Enhancing CDN with P2P
Hao Yin, Xuening Liu, Tongyu Zhan, Vyas Sekar, Feng Qiu, Chuang Lin, Hui Zhang, Bo Li
Article No.: 16
DOI: 10.1145/1823746.1823750

We present the design and deployment experiences with LiveSky, a commercial hybrid CDN-P2P live streaming system, which inherits the best of both CDN and P2P. We address several key challenges, including: 1) ease of integration with...

ELVIS: Entertainment-led video summaries
Arthur G. Money, Harry Agius
Article No.: 17
DOI: 10.1145/1823746.1823751

Video summaries present the user with a condensed and succinct representation of the content of a video stream. Usually this is achieved by attaching degrees of importance to low-level image, audio and text features. However, video content elicits...

Semi-supervised distance metric learning for collaborative image retrieval and clustering
Steven C.h. Hoi, Wei Liu, Shih-Fu Chang
Article No.: 18
DOI: 10.1145/1823746.1823752

Learning a good distance metric plays a vital role in many multimedia retrieval and data mining tasks. For example, a typical content-based image retrieval (CBIR) system often relies on an effective distance metric to measure similarity between...

Word level automatic alignment of music and lyrics using vocal synthesis
Namunu C. Maddage, Khe Chai Sim, Haizhou Li
Article No.: 19
DOI: 10.1145/1823746.1823753

We propose a signal-based approach instead of the commonly used model-based approach, to automatically align vocal music with text lyrics at the word level. In this approach, we use a text-to-speech system to synthesize the singing voice according...

Efficient delivery of on-demand video streams to heterogeneous receivers
Bashar Qudah, Nabil J. Sarhan
Article No.: 20
DOI: 10.1145/1823746.1823754

The number of video streams that can be serviced concurrently is highly constrained by the required real-time and high-rate transfers of multimedia data. Resource sharing techniques, such as Batching, Patching, and Earliest Reachable Merge Target...

Source traffic analysis
João V. P. Gomes, Pedro R. M. Inácio, Branka Lakic, Mário M. Freire, Henrique J. A. Da Silva, Paulo P. Monteiro
Article No.: 21
DOI: 10.1145/1823746.1823755

Traffic modeling and simulation plays an important role in the area of Network Monitoring and Analysis, for it provides practitioners with efficient tools to evaluate the performance of networks and of their elements. This article focus on the...
