Video summarization is receiving increasing attention due to the large amount of video content made available on the Internet. In this paper we present a novel idea to track video from multiple sources for video summarization. An algorithm that takes advantage of both video and closed caption text information for video scene clustering is described. Experimental results are given followed by di...

Source separation is becoming increasingly important in acoustical applications for spatial filtering. In the absence of any known source signals (blind case), a blind update equation similar to the natural gradient method [1] is presented, a derivative of which can be used in the case of known references (non-blind case). If some, but not all, source signals are known, blind-only algorithms ar...

It is widely recognized that a viable method to provide “anytime, anywhere” communication needs is by means of wireless technologies. In the indoor wireless environment, the 1-2 Mb/s wireless link technology that is currently available from several vendors (for example, WaveLan) will soon be replaced by higher capacities in the near future. For example, several manufacturers plan to develop rad...
