NEC Large data technology, can achieve a wide range of monitoring target analysis

Recently, NEC developed a http://www.aliyun.com/zixun/aggregation/13568.html "> Large data technology, can be applied to face recognition, character retrieval and other high-precision video analysis function of the surveillance camera system, By automatically adjusting the frequency of monitoring, the processing capacity on a single server will be 3 times times the former.

In the verification test, the human face, clothing and other characters and a variety of suspicious behavior analysis of the video surveillance system, after using NEC's large range of video processing technology, the data of 30 cameras can be analyzed on one server, which is 3 times times the original, which means that the NEC technology is applied in the same hardware as the server. , the scope of monitoring can be expanded to 3 times times.

In recent years, the airport, stations, streets and other widely set up a camera, the monitoring of data for automatic analysis and sampling of suspicious characters of the technical needs of increasing. When artificial visual sampling, as an auxiliary means, need to have a high degree of computing capacity of multiple servers to achieve high-precision video analysis processing, so the deployment of large-scale equipment in key areas has become an urgent problem to be solved.

NEC developed a large range of video processing technology, according to the camera monitoring video content, automatic control analysis of the pace of processing, for example, in the only need to analyze the character image, can adjust the importance of relatively weak analysis of the frequency of the scene, to improve the efficiency of processing.

The technology has the following characteristics.

1, according to the video content to judge the frequency of analysis and processing, improve efficiency.

According to the contents of the monitoring video, to control the actual analysis and processing. Priority to deal with the appearance of people, no portrait of the automatic reduction of analysis frequency, according to the location, time to adjust the analysis of frequencies, to maintain the accuracy of sampling, improve efficiency. Maximize the server's analytical processing to provide high accuracy video analysis for a wider range of monitoring areas.

2, adjust the processing efficiency according to the monitoring demand.

According to user needs, in the system to change the control analysis processing settings. Therefore, the need for analysis of the minimum range of video, as well as the immediate analysis of important areas, can be flexibly matched.

This technology integrates NEC's facial recognition technology and character retrieval technology, and can be applied to facilities and street monitoring devices around the world to achieve a wide range of system monitoring. NEC has been dedicated to video surveillance of large data processing technology, the technology is in a number of national empirical experiments in the hope of landing early application.
