Research on Online Sports Metadata Extraction System based on Video Processing Technology
Haixin Yao,Jinmei Shao 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.12
ports video metadata extraction system based on the content of basic goal use an automated or semi-automated interactive means to obtain video data as complete features and attributes for efficient retrieval mechanism. For fast access to video information needed, sports video ornamental create conditions. Firstly, video-based layered metadata description model, we discuss the structure of the video processing technology, and an increase in the time domain and airspace video object motion information on this basis. Low-level visual features for video and high-level semantic features presents a particular field of video information for video implicit hierarchical division method. Video automated visual feature extraction, semantic feature places marked attracted achieve human-computer interaction. Focus on the sports information descriptors and visual content descriptors, descriptor structure video. Video data based on hierarchical structure model and video features standard video content description model.

In order to investigate the influence of polyether ether ketone (PEEK) and its composite cage on the dry friction characteristicsof silicon nitride all-ceramic ball bearings, this paper firstly conducted a theoretical analysis of silicon nitride deep groove ballbearings subjected to radial load under dry friction conditions, and then conducted dry friction tests and simulation studieson PEEK, CF30 and PVX cage silicon nitride full ceramic ball bearings. The test results show that the temperature rise ofCF30 and PVX cage bearings is higher than that of PEEK cage bearings; the relationship between the root mean square valueof vibration of PEEK, CF30 and PVX cage bearings is PEEK cage bearings > CF30 cage bearings > PVX cage bearings; thesimulation model has good accuracy; Surface morphology analysis of the PVX cage bearing after the test show that thetransfer film has the effect of wear reduction and lubrication on the bearing. The results of the study have positive significancefor the research of transfer film lubricated bearings and the selection of cage materials.
