For a B/S based registration system, online photos collection is an important but difficult task, Because there are strict requirements of format that photos have to meet and the management of photos is complicated and likely to be in chaos if there is no good photo storage strategy. To solve those problems above, this paper presented an online photos collection component which contains two solutions: online-cam and local photo upload to allow candidates to submit photo online by themselves. First, it analyzed the principle and design process of flash based online-cam in detail, and then illustrated the implementation of both solutions proposed above. This component has already been used in several registration systems, and effectively simplifies staffs work and improves the quality of photos.
Aiming at the problem that most of weighted association rules algorithm have not the anti-monotonicity, this paper presents a weighted support-confidence framework which supports anti-monotonicity. On this basis, Boolean weighted association rules algorithm and weighted fuzzy association rules algorithm are presented, which use pruning strategy of Apriori algorithm so as to improve the efficiency of frequent itemsets generated. Experimental results show that both algorithms have good performance.
Study the basic theory and process of chaos particle swarm optimization (PSO) algorithm, improve the basic PSO algorithm by introducing the self-adaptive inertia weighting factor method. Construct the mathematical model of basic logistics scheduling to complete the simulation analysis experiments. Experiment results show that self-adaptive chaos particle swarm optimization algorithm is effective and feasible to solve the logistics scheduling model problem.
To the situation of hardness of Mybatis pagination, propose an interceptor based general physical pagination component. The component is designed by MVC(model-view-controller). Controller is realized using annotation based controller of Spring MVC. To design the business logic layer core method into general, DAO method custom and generic model was introduced. Interceptor was introduced into data persistence layer to realize physical pagination. JSP is used in page displaying. Give the detailed realization process of the component. Application results show that the proposed component has good generalization and portability, high execution efficiency and better flexibility.
Histogram equalization (HE) algorithm is wildly used method in image processing of contrast adjustment using images histogram. This method is useful in images with backgrounds and foreground that are both bright or both dark. But the performance of HE is not satisfactory to images with backgrounds and foregrounds that are both bright or both dark. To deal with the above problem, [ gives an improved histogram equalization algorithm named self-adaptive image histogram equalization (SIHE) algorithm. Its main idea is to extend the gray level of the image which firstly be processed by the classical histogram equalization algorithm. This paper gives detailed introduction to SIHE and analyzes the shortage of it, then give an improved version of SIHE named ISIHE, finally do experiments to show the performance of our algorithm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
