Single image dehazing based on dark channel prior may encounter color distortion in bright region (such as sky region). Three methods are proposed to overcome the limitations of original algorithm. A transmission threshold firstly was determined. Then, by using the threshold to correct the transmission map in different ways and make it adaptive to fog, three algorithms can effectively deal with the...
The k-Nearest Neighbor (k-NN) graphs are widely used in data mining and machine learning. How to construct a high quality k-NN graph for generic similarity measures efficiently is crucial for many applications. In this paper, we propose a new approach to effectively and efficiently construct an approximate k-NN graph. Our framework is as follows: (1) generate a random k-NN graph approximation, Gf,...
Interference management is an important problem in wireless networks. In this paper, we focus on the successive interference cancellation (SIC) technique, and aim to design an efficient cross-layer solution to increase throughput for multi-hop wireless networks with SIC. We realize that the challenge of this problem is its mixed integer linear programming formulation, which has bunches of integer...
Multipath Switching systems (MPS) are intensely used in state-of-the-art core routers to provide terabit or even petabit switching capacity. One of the most intractable issues in designing MPS is how to load balance traffic across its multiple paths while not disturbing the intraflow packet orders. Previous packet-based solutions either suffer from delay penalties or lead to O(N^2 ) hardware complexity,...
String matching is a basic problem of string operation, and privacy-preserving string matching, as a special case of secure multi-party computation, has broad applications in auction, bidding and some other commercial areas. In this paper, some protocols are proposed to solve this private matching problem, the security and correctness are analyzed respectively, and the actual efficiency is tested...
In this paper, we consider how to exploit multi-packet reception (MPR) to increase the capacity for a wireless sensor network. Since MPR behavior at the physical layer affects link layer scheduling, it is necessary to follow a cross-layer approach to obtain an optimal solution. Due to the complexity of cross-layer optimization, although MPR has great potential to increase capacity, optimal solutions...
Super long integers which are outside the confines of numbers defined in existent program language compilers or interpreters are widely employed in cryptographic applications. The paper designs 10 algorithms, which almost all address operands by the byte, and are used for the operation of unsigned super long integers, including conversion, shift, comparison, addition, subtraction, multiplication,...
The paper gives the definition of consistency of interval number complementary judgement matrix, structuring object function, it gets the interval weight. Furthermore, it gets a simple method for checking the consistency of interval number complementary judgement matrix without having to solve linear program. Finally, a numerical example is given to illustrate the use of this method.
Efficiency and effectiveness are always the emphases of a scheduler, for both link and processor scheduling. Well-known scheduling algorithms such as surplus round robin (SRR) and elastic round robin (ERR) suffer from two fold shortcomings: 1) additional pre-processing queuing delay and post-processing resequencing delay are incurred due to the lack of short-term load-balancing; 2) bursty scheduling...
