The Method Of Image Content Retrieval Under The Triple-play Service

With the rapid development and integration of telecommunications networks, Internet network and broadcast networks, the transformation of information technology, functional differences between the three major networks are getting smaller business closer and closer, triple play time has come. Triple play not only brought benefits to the public information services, it also brings huge amounts of data free circulation problems. Since the data source of the outside world, a direct result of the difficulty of monitoring the infinite content increased. But in the era of triple play, network technology really has become the people's daily life essential, which means that the content of the regulation of people's lives and ideas of great significance. After the contents of the triple play of the implementation of regulatory policies, content covered include violence, pornography,anti-government and endanger national security information generation and dissemination.But on such a large scale unstructured data regulate mature technology so far there has been no monitoring of big data management control are also just started not even on the road. "Triple play broadcasting content regulation system," research project thus generated.Based independent research and development of content regulation system HUSTRIM triple play, the main radio and television images and real-time data for a large number of these characteristics, the mass of information presented to the triple play after regulation. Based a detailed study of the radio and television image content retrieval environmental conditions and trends, it describes the domestic and international dynamics of the image retrieval system before a preliminary knowledge and understanding.Proposed the use of an image feature just described drawbacks image index value, while in-depth research and analysis of the existing typical image retrieval techniques, including image feature extraction and image indexing technique described value method, the area is split color feature and not variable torque characteristic shape combination image feature retrieval and application of this method to HUSTRIM image content retrieval subsystem,and then design and implement HUSTRIM of radio and television content image retrieval subsystem--HUSTRIM-GR.Experiments show, HUSTRIM-GR integrated color, space and shape image retrieval method can achieve better radio and television image retrieval. It only overcome the limitations of using single feature retrieval, improve the accuracy of search and retrieval of versatility, its performance is better.
