Existing public security video surveillance system exists three major defects

1 November, at its twelfth session, held in fair, gonganbudisanyanjiusuo Merlin, turning to face the public security information for monitoring video technology, said that, at present, with the monitoring network-scale is continually expanding and surveillance video applications, the existing public security video surveillance system is already insufficient to meet the needs of the police, a line-policemen for video surveillance network performance and the technical means to put forward higher requirements, mainly in three respects:

First, the monitoring network of image quality and a gap between the demands of case handling.

This issue arose in addition to the part of the quality of the camera Terminal capture needs to increase, one important reason is that in order to save storage space and transport costs, the video images are often large compression, decoding, details missing, many on the detection of useful information with data compression and loss.

Secondly, monitor network application without a smart technology.

Video surveillance network video content analysis also rely on artificial access real-time viewing, manually. With the expansion of the scale of monitoring networks, a massive growth of video data, image monitoring and access to a large amount of manpower, become restricted full video surveillance network performance bottlenecks. From mass-surveillance video get useful information or intelligence has become increasingly difficult. From a practical point of view of the application, the information should be retrieved and the query and the current application of the surveillance video is mostly just a reproduction of the scene to monitor and playback, it is difficult to meet modern security information application needs.

Third, video data mainly in monitoring designed online transfer, you cannot truly and police network data sharing between.

Monitoring of the equipment in the network number of the camera is very large, and whether real-time viewing or subsequent video file browsing, users can only access a small part of video resources, and limited to network bandwidth, the shared application could not be large. Similarly, other sectors of society's video surveillance data can not be achieved on the public network users access and sharing. This has caused a large amount of video data is a one of the islands of information, not fast and effective reach the hands of the police investigation.

Merlin Dr said, in response to the above questions, submit a surveillance video gonganbudisanyanjiusuo structured description of technical solutions.

Video is a structured description of how to video (unstructured data) to retrieve employee successive application of technology in depth. Surveillance video structured description of key technologies include surveillance video keyframe extraction and video summary, image feature extraction techniques, intelligent video analysis technology, chip technology and embedded devices, monitors, video structured description of the standard system, and so on five key technology.
