Stream data mining has gained a lot of attention over the last years due to an abundance of streaming data in professional as well as personal applications. Solutions have been proposed for many mining tasks such as clustering, classification, frequent item set mining and aggregation. Stream mining is especially challenging due to the large (usually endless) amount of data and the time constrai...

In recent years due to various kind of social activities such as theft, bomb attack and other terrorist attack preventive security measures at public places has gained lot of importance. Abandoned Object detection is most crucial task in visual surveillance system. Many Public or open areas are facilitated with cameras at multiple angles to monitor the security of that area for keeping citizens...

The problem of estimating frequency moments of a data stream has attracted a lot of attention since the onset of streaming algorithms [AMS99]. While the space complexity for approximately computing the p moment, for p ∈ (0, 2] has been settled [KNW10], for p > 2 the exact complexity remains open. For p > 2 the current best algorithm uses O(n1−2/p logn) words of space [AKO11,BO10], whereas the l...

With advent of internet, there has been tremendous surge in search for videos. Research suggests that users spend a lot of time browsing: viewing part of one video after another while watching only a few of the videos to its completion. This is termed as seek, a special form of browsing repeating partial viewing of the same video. This impacts the network bandwidth resulting in streaming issues...

As the rapid growth of wireless IP networks, wireless IP access networks have a lot of potential applications in a variety of fields in civilian and military environments. Many of these applications, such as realtime audio/video streaming, will require some form of end-to-end QoS assurance. In this paper, an algorithm WMPLD (Wireless Multimedia Packet Loss Discrimination) is proposed for multim...

Video coding is present in a lot of multimedia applications such as video conferencing, digital storage media, television broadcasting, and internet streaming. However, offering universal access to video content is far from trivial when taking into account the diversity of current networks and terminals. In this paper, we will discuss how MPEG-21-based technology can be combined with a recently...
