This paper constructs a flexible person identity authentication archetype by using multiple identity verification methods, which take effort to combine the advantages of both traditional and biometric authentication ways while overcome their respective weaknesses. By introducing fuzzification of the penalty and different cost algorithm, we can alleviate over-fitting problem and corrects the class-boundary-skew...
In this paper, the requirements of survivability of MultiHop Wireless Network (MWNeT) was analyzed firstly, then we classify the impacts that affect survivability into three categories: dynamic topology, faults and attacks, and the impacts of these factors are analyzed individually. A simulation environment for the MWNeT towards survivability is designed and implemented as well. Experiments that under...
BP algorithm is a very important and classic learning algorithm. It have a wide range of applications in pattern recognition, image processing and analysis and control areas. However, in practice, we found that BP algorithm still have inadequates, such as the algorithm's convergence is slowly, easy to converge to local minimum points, but not the overall optimal, Multiple iterations, numerical stability...
Program slicing provides a new way to software maintenance, program understanding. It can give the programmer the statements only relevant to the computation of a given function. It can transform a large program into a smaller one. A program slicing respected with a point of interest is not only relevant on the variables which are defined or used by the interesting point, but also relevant on the...
DBC (Differential Box-Counting) has been proved the least complex and the most convenient way to calculate the fractal dimension of images. However, for images with low resolution, the existence of empty boxes will influence the accuracy of fractal dimension. In order to reduce its effect, a new approach ADBC (Actual Differential Box-counting) is proposed in this paper. First, the empty boxes are...
Component-based software development (CBSD) has been viewed the future trend in software development due to not only saving the time and cost of system development, but also increasing the reliability and maintainability of the system. It is thought to be one of the most important approaches to solve software crisis. We propose a method for CBSD in this paper, where the coupling between components...
This paper analyzes the inflexibility of video data collection for current 3G video phones. A solution for adaptive video data collection is proposed. The solution proposed in this work mainly consists of software components, according to which hardware needs to be selected. It also gives the video phone terminal structure, block diagram for H.324M video phone terminal, the main software functional...
As K-means Clustering Algorithm is sensitive to the choice of the initial cluster centers and it is difficult to determine the cluster number and it is easy to be impacted by isolated points, propose the K-means multiple Clustering Method Based on Pseudo Parallel Genetic Algorithm. In the method, adopt the strategy of Variable-Length Chromosome real-coded. Through the introduction of chromosome retreading...
