The technology of target data association is the premise and foundation of target tracking and information fusion, for the association quality will directly affect the accuracy and rationality of the subsequent information processing. In the fuzzy synthetic method, the Euclidean distance of target position and velocity are used as the fuzzy factor set, and the membership degrees are calculated through...
Distributed camera networks represent an emerging trend for the incorporation of mobile smart cameras in next generation large-scale surveillance systems. To achieve the great benefits of mobile smart camera, two challenging issues, the limited computational capabilities of a smart camera and the energy constraints of its battery-powered mobile platform, should be faced. This paper investigates the...
Dynamic spectrum auction (DSA) is a promising market mechanism to stimulate primary users (PUs) to lease their idle spectrum resources to improve their revenue. In this work, we focus on dynamic spectrum auction design which considers both space and time properties of spectrum. We propose a dynamic spectrum auction platform, where secondary users (SUs)enter a spectrum trading stochastically and spectrum...
The limitation and improvement of MKGA-BP are mainly discussed in this paper. The improved algorithm could simplify the original parameters by increasing the amount of random entries. The results of the improved algorithm can achieve the desired goal with a lot of experiments. Then the new algorithm is applied to the model of Chinese word segmentation. It is proved that the improved algorithm is better...
In this comment, several errors in Chlamtac et al., 1996, Lightpath (Wavelength) Routing in Large WDM Networks and one error in Xu et al., 2000, Dynamic Routing and Assignment of Wavelength Algorithms in Multifiber Wavelength Division Multiplexing Networks are pointed out. We present corrections to the errors.
In this paper, we address these challenges in real-world unconstrained environments where the background is complex and dynamic. In the algorithm proposed, we extract the features in a color space, accumulate the feature information over a short time, and fuse high-level knowledge and low-level feature information. A fuzzy technique is also developed to detach silhouettes of moving objects from a...
We present a study on the static resource allocation in lightpath routed WDM networks, where each request is associated with a service grade. The goal is to maintain certain acceptance ratios for the requests of all grades, as well as to minimize the resource consumption. We propose a model of static grade-of-service (GoS) differentiation as minimizing the total rejection and cost penalty. Then, we...
Various static resource allocation algorithms have been used in WDM networks to allocate resources such as wavelength channels, transmitters, receivers, and wavelength converters to a given set of static lightpath demands, based on certain design objectives. However, although optimized resource allocations can be obtained, it remains an open issue how to determine which resources are bottlenecks to...
