Design Patterns Based Design And Implementation Of The Human Face Information Certification System

Design pattern is a general solution to a specific problem encountered during the process of software design. The purpose of using these design patterns into the process of software design and development is to make use of successful experience summarized by former developers. They are successful architecture, design and implementation strategies. By realizing these design patterns, people can make use of successful design and architecture easily and process of design becomes fairly more convenient. The most important goal of design pattern is to help people to design more excellent software.During the process of design and development of this human face recognition system, many design patterns are implemented to solve problems. Regarding the operational characteristics of human face recognition system, the requirement for design pattern is put forward. The design pattern referred by this article is object-oriented design pattern. The paper uses a great deal UML figures to describe patterns' structure. In this paper, the work done by the following: 1) Researching of design patterns technology. Carried out a chapter in the application of design patterns before the design technology, including the design mode of thinking, the design of the classification model, and found that the use of design patterns, and other methods; 2) Face certification system analysis and design. Analyzing the process of face recognition systems and methods to explore the various stages of face recognition systems work to be done by, the system needs analysis, system analysis on the basis of the system design, including the module into , Process analysis, system deployment, and so on; 3) Applying of several typical patterns in the system. Widely used in the design of the object-oriented programming application in the design pattern technology, design patterns through the application of technology, the system has a very good maintainability and a high degree of flexibility, and other characteristics in order to facilitate the study of the theory as the result of an in-depth development So that the system needs change or as a result of user demand brought about by changes in the system upgrade, the system can be widely used in a variety of face recognition technology to carry out a comprehensive, so as to the merits of the use of technologies to improve the accuracy of the system; 4) System implementation and testing. Giving the use of C + + programming language to realize the design method, the application gives the design of the system after some type of code structures; 5) Summary and outlook. Through systematic analysis, design, the design pattern in the system, in the chapter on face recognition system to understand, model design technology and research on the basis of the full text of sum up, this article points out the shortcomings and work to be done.By analyzing the system, the concrete method and design solution are given. The disadvantage and possible improvement of system are pointed out.
