Exploring many-to-one speech-to-text correlation for web-based language learning
Herng-Yow Chen, Sheng-Wei Li
Article No.: 13
DOI: 10.1145/1236471.1236472

This article investigates the correlations between multimedia objects (particularly speech and text) involved in language lectures in order to design an effective presentation mechanism for web-based learning. The cross-media correlations are...

Efficient sampling of training set in large and noisy multimedia data
Surong Wang, Manoranjan Dash, Liang-Tien Chia, Min Xu
Article No.: 14
DOI: 10.1145/1236471.1236473

As the amount of multimedia data is increasing day-by-day thanks to less expensive storage devices and increasing numbers of information sources, machine learning algorithms are faced with large-sized and noisy datasets. Fortunately, the use of a...

Critical causal order of events in distributed virtual environments
Suiping Zhou, Wentong Cai, Stephen J. Turner, Bu-Sung Lee, Junhu Wei
Article No.: 15
DOI: 10.1145/1236471.1236474

We investigate the causal order of events in distributed virtual environments (DVEs). We first define the critical causal order relation among the events. Then, we propose some mechanisms to enhance the prevalent RO (receive order delivery)...

Segmentation and recognition of motion streams by similarity search
Chuanjun Li, S. Q. Zheng, B. Prabhakaran
Article No.: 16
DOI: 10.1145/1236471.1236475

Fast and accurate recognition of motion data streams from gesture sensing and motion capture devices has many applications and is the focus of this article. Based on the analysis of the geometric structures revealed by singular value...

An open architecture for transport-level protocol coordination in distributed multimedia applications
David E. Ott, Ketan Mayer-Patel
Article No.: 17
DOI: 10.1145/1236471.1236476

We consider the problem of flow coordination in distributed multimedia applications. Most transport-level protocols are designed to operate independently and lack mechanisms for sharing information with other flows and coordinating data transport...

Robust content-based MPEG-4 XMT scene structure authentication and multimedia content location
Ziad Sakr, Nicolas D. Georganas
Article No.: 18
DOI: 10.1145/1236471.1236477

For the past decade, there have been numerous research works focusing on the protection of digital images, audio, video, 3D virtual scenes, and software data from unauthorized use and distribution. With the emerging technology of the MPEG-4...
