Based Video Retrieval Secondary Vocational Schools Network Learning Platform

Along with multimedia technology, the development of computer network technology and the continued growth of the information needs of the people, and therefore, most of the various information systems, according to information from the media, in which multimedia information, the video data account for a large proportion. As people increasingly widespread use of digital video in various fields, and video information presentation grow geometrically, the previous search methods and systems management become increasingly unable to meet the demand. Based on this, mainly based video retrieval, secondary vocational schools network learning platform for design and analysis. The main contents are as follows:The first is the introduction, by reading a lot of literature and the collection of data, referred to the research background, current development of open and distance education at home and abroad as well as e-learning systems analysis and explain the source of this thesis, the final chapter in accordance with the above theory overview summarizes the main contents of this paper; followed by needs analysis, from business analysis, functional analysis, implementation feasibility analysis of three aspects of this chapter for detailed overview; once again is the overall design, according to the system design model, the system needs analysis based on the overall structure of the framework to build, mainly in the following four areas:System development environment configuration, system design techniques, system architecture, system design with overall functional modules; followed by detailed design, based on the second chapter and Chapter III requirements analysis and design, system design brief overview and complete the analysis and design of each subsystem functional modules. Then the system implementation, designed and constructed in accordance with the model of each subsystem modules for analysis and design, the use of systems development tools, sets forth specific network learning platform; Finally, the test objectives and test content system. This graduation design work and a summary and outlook.
