The Design And Implement Of Sharing Website Based On Near-duplicate Web Video Detection

In recent years, with the scale of online video sharing site and computer technology, multimedia technology continues to evolve; the Web Video was sought after by more and more Internet users. at the same time, There is a lot of duplication (duplicate) or near duplicate (near-duplicate) videos on the same sharing site, It brings in a lot of difficulties and inconvenience and Consume a large amount of network resources, also affect the user's search efficiency and user experience. Therefore, in order to improve sharing site resource utilization and efficiency of video retrieval, the efficient application of duplicate web video detection algorithm is very necessary.The main work is to use J2EE technologies and open source SSH framework design and implementation a video video sharing sit with a duplicate video detection .The system is to follow the software engineering standards and processes for development, using object-oriented methods and techniques to complete system analysis and design, including requirements analysis, architecture design, and database design ,and user J2EE technology to achieve basic functions of the web site, include uploading video, video query, video maintenance ,playback video and user management. In additional,The difference with other vide sharing site is: the system has video duplication detection, we use JNI to call SLC+NNS algorithm to complete duplication detection, After video uploading, the system will automatically return the detection results, and it can prevent the duplicate video from uploading to sharing sites. In order to improve detection efficiency, we run the shot boundary detection and features extraction at the same time, it can reduce the time loss because of reading video file repeat .we also joined the LSH approximate nearest neighbor query technology to improve system performance.Now we have completed a prototype of video-sharing site with duplication video detection function, and This system has the basic functions of general video-sharing site, but also provides video duplication detection, and in this respect good results. The system has been able to basically meet the actual demand; video duplication detection algorithm is a practical application, but also to explore and study a video duplicate detection algorithm test platform.
