Content-adaptive digital music watermarking based on music structure analysis
Changsheng Xu, Namunu C. Maddage, Xi Shao, Qi Tian
Article No.: 1
DOI: 10.1145/1198302.1198303
A novel content-adaptive music watermarking technique is proposed in this article. To optimally balance inaudibility and robustness when embedding and extracting watermarks, the embedding scheme is highly related to the music structure and human...

Goal-oriented optimal subset selection of correlated multimedia streams
Pradeep K. Atrey, Mohan S. Kankanhalli, John B. Oommen
Article No.: 2
DOI: 10.1145/1198302.1198304
A multimedia analysis system utilizes a set of correlated media streams, each of which, we assume, has a confidence level and a cost associated with it, and each of which partially helps in achieving the system goal. However, the fact that at any...

Video abstraction: A systematic review and classification
Ba Tu Truong, Svetha Venkatesh
Article No.: 3
DOI: 10.1145/1198302.1198305
The demand for various multimedia applications is rapidly increasing due to the recent advance in the computing and network infrastructure, together with the widespread use of digital video technology. Among the key elements for the success of these...

Virtual videography
Rachel Heck, Michael Wallick, Michael Gleicher
Article No.: 4
DOI: 10.1145/1198302.1198306
Well-produced videos provide a convenient and effective way to archive lectures. In this article, we offer a new way to create lecture videos that retains many of the advantages of well-composed recordings, without the cost and intrusion of a video...

Multimedia simplification for optimized MMS synthesis
Wei-Qi Yan, Mohan S. Kankanhalli
Article No.: 5
DOI: 10.1145/1198302.1198307
We propose a novel transcoding technique called multimedia simplification which is based on experiential sampling. Multimedia simplification helps optimize the synthesis of MMS (multimedia messaging service) messages for mobile phones....

Detecting social interactions of the elderly in a nursing home environment
Datong Chen, Jie Yang, Robert Malkin, Howard D. Wactlar
Article No.: 6
DOI: 10.1145/1198302.1198308
Social interaction plays an important role in our daily lives. It is one of the most important indicators of physical or mental changes in aging patients. In this article, we investigate the problem of detecting social interaction patterns of...
