Video streaming using a location-based bandwidth-lookup service for bitrate planning
Haakon Riiser, Tore Endestad, Paul Vigmostad, Carsten Griwodz, Pâl Halvorsen
Article No.: 24
A lot of people around the world commute using public transportation and would like to spend this time viewing streamed video content such as news or sports updates. However, mobile wireless networks typically suffer from severe bandwidth...
This article describes a method for the automatic evaluation of video summaries based on the training of individual predictors for different quality measures from the TRECVid 2008 BBC Rushes Summarization Task. The obtained results demonstrate...
Sparse transfer learning for interactive video search reranking
Xinmei Tian, Dacheng Tao, Yong Rui
Article No.: 26
Visual reranking is effective to improve the performance of the text-based video search. However, existing reranking algorithms can only achieve limited improvement because of the well-known semantic gap between low-level visual features and...
An information-based dynamic extrapolation model for networked virtual environments
Xin Zhang, Tomás E. Ward, Séamus Mcloone
Article No.: 27
Various Information Management techniques have been developed to help maintain a consistent shared virtual world in a Networked Virtual Environment. However, such techniques have to be carefully adapted to the application state dynamics and the...
Content-based web image retrieval based on the query-by-example (QBE) principle remains a challenging problem due to the semantic gap as well as the gap between a user's intent and the representativeness of a typical image query. In this article,...
A control theoretic scheme for efficient video transmission over IEEE 802.11e EDCA WLANs
Paul Patras, Albert Banchs, Pablo Serrano
Article No.: 29
The EDCA mechanism of the IEEE 802.11 standard has been designed to support, among others, video traffic. This mechanism relies on a number of parameters whose configuration is left open by the standard. Although there are some recommended values...
A joint layered scheme for reliable and secure mobile JPEG-2000 streaming
Xinglei Zhu, Chang W. Chen
Article No.: 30
This article presents a novel joint layered approach to simultaneously achieve both reliable and secure mobile JPEG-2000 image streaming. With a priori knowledge of JPEG-2000 source coding and channel coding, the proposed joint system integrates...
