MultiFusion: A boosting approach for multimedia fusion
Xiangyu Wang, Mohan Kankanhalli
Article No.: 25
DOI: 10.1145/1865106.1865109

The multimodal data usually contain complementary, correlated and redundant information. Thus, multimodal fusion is useful for many multisensor applications. Here, a novel multimodal fusion algorithm is proposed, which is referred to as...

Multimedia sensor fusion for retrieving identity in biometric access control systems
Girija Chetty, Matthew White
Article No.: 26
DOI: 10.1145/1865106.1865110

In this article, we propose a novel multimedia sensor fusion approach based on heterogeneous sensors for biometric access control applications. The proposed fusion technique uses multiple acoustic and visual sensors for extracting dominant...

Dialocalization: Acoustic speaker diarization and visual localization as joint optimization problem
Gerald Friedland, Chuohao Yeo, Hayley Hung
Article No.: 27
DOI: 10.1145/1865106.1865111

The following article presents a novel audio-visual approach for unsupervised speaker localization in both time and space and systematically analyzes its unique properties. Using recordings from a single, low-resolution room overview camera and a...

Spatial-geometric approach to physical mobile interaction based on accelerometer and IR sensory data fusion
Abu Saleh Md Mahfujur Rahman, M Anwar Hossain, Abdulmotaleb El Saddik
Article No.: 28
DOI: 10.1145/1865106.1865112

Interaction with the physical environment using mobile phones has become increasingly desirable and feasible. Nowadays mobile phones are being used to control different devices and access information/services related to those devices. To...

Optimizing consistency by maximizing bandwidth usage in distributed interactive applications
Damien Marshall, Séamus Mcloone, Tomás Ward
Article No.: 30
DOI: 10.1145/1865106.1865114

A key factor determining the success of a Distributed Interactive Application (DIA) is the maintenance of a consistent shared virtual world. To help maintain consistency, a number of Information Management techniques have been developed. However,...

Understanding overlay characteristics of a large-scale peer-to-peer IPTV system
Long Vu, Indranil Gupta, Klara Nahrstedt, Jin Liang
Article No.: 31
DOI: 10.1145/1865106.1865115

This article presents results from our measurement and modeling efforts on the large-scale peer-to-peer (p2p) overlay graphs spanned by the PPLive system, the most popular and largest p2p IPTV (Internet Protocol Television) system today. Unlike...
