Multimedia database retrieval is a key technology used to construct a modern digital museum. The antique coin images are the important component parts of multimedia database in digital museum. In this paper, we design an antique coin image retrieval (ACIR) system using synthetic features. The synthetic features include two parts: one is the histogram of centroid distance (HCD) as a coarse feature...
The distribution of αX + βY has been studied by several authors especially when X and Y are independent random variables and come from the same family. However, there is relatively little work of this kind when X and Y are correlated random variables. Based on this consideration, in this paper, we takes bivariate standard normal distribution which is widely applied in our life as an example, derive...
For mining new pattern from evolving data streams, most algorithms are inherited from DenStream framework which is realized via a sliding window. So at the early stage of a pattern emerges, its knowledge points can be easily mistaken as outliers and dropped. In most cases, these points can be ignored, but in some special applications which need to quickly and precisely master the emergence rule of...
Implementing the dynamic couple of searching paths and resource allocation becomes increasingly important in the research of Quality of Service (QoS) routing. In this paper, we formulate the problem of dynamic QoS routing with resource allocation based on Worst-case Fair Weighted Fair Queuing (WF2Q) packet scheduling style. We propose an algorithm using the proved results - the optimal path resource...
Distinguishing potential new cluster data from outliers is a main problem in mining new pattern from evolving data streams. Meanwhile, all the clustering algorithms inherited from CluStream framework are distribution-based learning which are realized via a sliding window, so this problem becomes more obvious. This paper proposes a three-step clustering algorithm, rDenStream, based on DenStream, which...
How to provide a broad range of QoS guarantees in a packet network is an important issue. In order to achieve QoS guarantees, good traffic schedulers are indispensable. In this paper, a packet scheduling discipline UBSFQ and its simulation are proposed. According as the implementation and result of our simulations, this scheduling discipline is computational efficient, and can resolve the unstable...
