This paper quantifies the effect of “word-of-mouth” marketing strategy on pricing decisions in a competing duopoly market. Assuming that consumer arrivals follow a Poisson Process, a consumer's purchasing decision depends on his individual judgment and probability of his friends' existing selections, who connect to him in a ‘scale-free’ social network. Firms then make pricing decisions responding...
Highlight detection is a challenge task in soccer video analysis. Using Web-casting text as external knowledge is proved to be a short cut to achieve both efficiency and effectiveness. Based on the previous framework using Web-casting text, we have improved the processes of video time detection and highlight boundary detection. Our method can detect the transparent time bar and can achieve acceptable...
Web video databases tend to contain tremendous near-duplicates with the explosive growth of online videos. How to detect and eliminate these near-duplicates has become an essential problem for Web video storage and indexing. In this paper, we propose a hierarchical approach to solve this problem efficiently and effectively. For an incoming video, firstly we compare global features to exclude videos...
Internet videos have grown exponentially with the help from video sharing Websites. Automatic topic mining is therefore increasingly important for organizing and navigating such large video databases. Most of current solutions of topic detection and mining were done on news videos and cannot be directly applied on Web videos, because of their limited and noisy semantic information. In this paper,...
The synchronization between audio and video during their transmission and play out has become one of key issues of Internet multimedia applications. In this paper, a new scheme for synchronized coding of audio and video is proposed. In the encoder, audio bits are embedded into transformed coefficients of video as hiding signal, and then the hybrid information is encoded simultaneously. In the decoder,...
The amount of information on the Web is growing at an exponential rate. Information overload has brought a heavy burden for modern life. Keyword based search engines no long fill the needs of many people. This paper introduces an approach towards intelligent information retrieval by providing clustered Web pages and minded concepts based on results of search engines. Web page clustering is based on...
Fault tolerance schemes can be used to increase the availability and reliability of network service systems. One aspect of such schemes is failover - the reconfiguration of available resources and restoration of state required to continue providing the service despite the loss of some of the resources and corruption of parts of the state. Most of the techniques used for increasing the availability...
