A consensus-based distributed algorithm is described for solving a linear algebraic equation. Unlike a previously proposed algorithm for solving the same problem, the one proposed in this paper does so with any arbitrary initialization. In addition, the algorithm contains design parameters which may be chosen to optimize convergence rate.
Flight rerouting is an important strategy in the airspace with the limit of heavy weather and flight conflict. First, the grid method was utilized to build the model for diverting airspace environment based on numerical weather prediction features in severe weather. In considering the air traffic rules and aircraft performance, a new rerouting path planning method based on the improved ant colony...
Markov random fields (MRF) can be used for a wide variety of vision problems. In this paper we will propose an algorithm of scenes feature description and analysis based on MRF. The theoretical framework is based on MRF and Bayesian estimation via the energy optimization. We analyze the texture feature. Using MRF to modeling on the image, then combine with texture information and use of Bayesian to...
Based on the relaying scheme which permits the relay node to jointly encode the data information from two source nodes, a new network low density parity check (NLDPC) code is designed for the Rayleigh fading channel. Since the log-likelihood ratio (LLR) of the signal received from the fading channel is not a Gaussian random variable, the Gaussian Approximation algorithm cannot be employed directly...
Extracting the association rules is an important research topic among the various data mining problems. Based on the rough set theory which is a powerful tool in dealing with incompleteness and uncertainty, an algorithm to mine association rules in incomplete information systems is presented. In the new algorithm, the support and confidence are redefined and a new judgment criterion is introduced...
With the development of network and multimedia technologies, information hiding in video streams has played an important role in the steganographical field, and correspondingly video steganalysis techniques are catching attention of the security department of each government. In this paper, MSU StegoVideo, a public video steganographic tool is analyzed deeply. A new steganalysis algorithm, which uses...
