How does face recognition technology work in the * system?
The face recognition system is hot and can be applied to all walks of life. This article will introduce you to some applications of the ID face recognition system in the * system.
Face recognition system features
Face recognition photo comparison system for rapid identification, in a large number (a few thousands to several million) of the database (photographs of missing people photo library, captured persons photo library, permanent population photo library, temporary population photo library, chase Photographs of fugitives, photobanks of key populations, photobanks of CCIC fugitives, etc.) Find and retrieve the identity of specific individuals. Supports photo-to-photograph, video streaming, photos streaming, video streaming, and more. It is possible to perform photo comparisons and identity verification on local area networks, intranets, and the Internet.
The face recognition photo comparison system extracts face information in the photo and transmits it through a dedicated network service platform. The server side compares the face information in the photo with the face information in the business personnel database within the specified range. Right, then identify the person who is “similar†in the photos and get their detailed information.
Face recognition system application range and direction
The system is mainly applied to the national judicial system, the system, and the prison system. For example, a comparison center is set up at the provincial, city, and city bureaus, and a comparison client is established at a branch office, a police station, or a criminal investigation center, or a cell phone and a mobile phone via GPRS/CDMA. PDA takes photos and sends photos to compare requests. It makes full use of very valuable face photo clues, greatly accelerating the process of the identification of suspects by investigators, and in order to speed up the process of “enhancement of science and technology†and form a highly intelligent, socialized, and large-scale prevention system. Provides effective technical means.
The system focuses on the registration and management of captured personnel, online pursuit, comparison and verification, and post-processing. At the same time, portrait comparisons can also be used in criminal investigations and maintenance of social stability. The application direction is as follows:
- System captures at-risk criminals: Face-based photo comparison system helps to speed up identification of suspects, reduces inefficiencies of "human tactics", and exerts tremendous energy in applications such as pursuit, detection, and tracing. .
- Seeking and tracing: Photographs provided by ordinary people or other business departments are sent directly to the system for comparison, retrieval, and screening, and finally confirmed manually.
- The police station has seized the offenders: the personnel who have been stopped by the police station, registration transcripts, and for some of the ethnic minorities, deaf and mute persons, or those who remain silent, who cannot verify their identity, can take photos and compare them with various photo banks. Investigate personnel involved in major cases so as not to evade the net; or check their previous records and accumulatively handle them.
- Verification of unnamed corpse: When an unnamed corpse needs to be verified, the frontal photograph is taken first and sent to the computer. If the photograph is closed, broken or deformed, a portrait photograph can be drawn using a portrait synthesis system or manually, and the comparison system is sent to the comparison system. Verification.
- Eyewitness description: After obtaining the image description of the suspect by the witnesses on the spot, the portrait synthesis system can be used for investigation.
-Acquisition of video surveillance photos: The general surveillance system for the scene, the suspects involved in the image are fuzzy, deflection, reverse light and other poor quality issues, then need to be based on the image portrait synthesis system or manually draw a standard photo , Check in the photos to compare with the system.
- Meetings in public places: In public places such as the government and stadiums, there are frequent personnel troubles. At this time, the civilian police cannot directly deal with people. You can use a telephoto camera to take close-up shots. If the effect is not good enough, you can correct it with the portrait synthesis system. In comparison with the system verification.
- Identification of first-generation/second-generation resident ID cards: According to photo ID information of criminals, the information in the photo library of the system is compared with the information in the photo library of the system. Information similar to the photos on the documents can be extracted to make full use of the existing second generation. ID photo resources provide efficient and beneficial help for the work of the department.
- Missing population surveys, shelters, compulsory detoxification, customs clearance, etc. The photo comparison system helps improve work efficiency and greatly reduces the strength of manual comparisons.
- Other applications: comparison of resident population, comparison of temporary population, comparison of key population, comparison of CCIC fugitives, etc.
Intelligent face recognition analysis technology, to achieve accurate calculation and retrieval of tens of millions of photo library, screening of required personnel information, and to ensure that the analysis results can meet the requirements of manual secondary analysis processing.
