An effective color image fusion algorithm based on NSCT(Nonsubsampled contourlet transform) and Lαβ color space is proposed for visual and infrared night image fusion, aiming at traditional fusion method suffering from no rich details and no clear target. The NSCT is applied in fusion processing because of its good properties which include multi-scale, time-frequency localization, shift invariance,...
The discretization problem of continuous attribute is an important topic of machine learning, and data preprocessing. The discretization algorithm based on dynamic hierarchical clustering proposed in the paper is an improvement of hierarchical clustering algorithm. First, the qualitative analysis of the algorithm is made. Second, clustering analysis of the random collection data according to the similarity...
Coverage holes often exist in wireless sensor networks deployed with static nodes. In order to patch the holes and recover the network performance, an algorithm based on mobile nodes is presented, which guides the mobile nodes to the position of holes, and then get the resilient coverage. The static sensors bound a coverage hole can compute the optimum position for the mobile sensors which, after...
Every user has a distinct background and a specific goal when searching for information on the Web. The goal of Web search personalization is to tailor search results to a particular user based on that user's interests and preferences. This paper presents an approach of search engine optimization based on algorithm of BP neural networks aiming at meeting the increasing requirements of modern people...
In view of the blur operation in the image tamper, a blur image blind identify algorithm based on the edge feature was proposed. Firstly, the algorithm made the logarithm operation to the image according to the edge feature of out-of-focus blur and artificial blur, and separated image's the incident component and the reflection component. Then it used homomorphism filter to the wavelet region, and...
This paper studies a supply chain quality coordination and risk-sharing problem. We find when the supply chain is coordinated under internal and external quality fault existing, it can be obtained the optimal profit, order quantity and risk sharing of the supply chain parties for each. And when the supply chain is coordinated and the item has not been sold, the supplier should allow the seller return...
Theory of evidence is a kind of effective treatment methods for uncertain information fusion. However there will be problems in the fusion results based on the classical D-S combination when the evidence serious conflict or completely conflict. This paper proposes a kind of effective combination of fusion conflict evidence. At first a distance function was introduced. Then the similarity of evidence...
In reality, the paper money number recognition is significant, which can effectively prevent the illegal trade of paper money. First, this paper makes pretreatment to the paper money, and then for the rapidity and accuracy requirements, a new identification method is presented which based on intersection change and the distance difference between the two points of the character on the special location...
To solve the problem of slow convergence speed of the standard genetic algorithm (SGA), the strategy of adaptively changing the search area is used to reduce the search area progressively in this paper. The tactics of concerted evolution among multiple populations is proposed aimed at the deficiency of easily plunging into a local optimal solution of SGA. Distant hybridization strategy and a new method...
In this paper, we introduce and study a new system of variational inclusions with (A, eta) accretive operators in real q-uniformly smooth Banach spaces. By using the resolvent operator technique associated with (A, eta) accretive operators, we construct some new iterative algorithm for approximating the solution of this system of variational inclusion. And we prove the existence and uniqueness of...
