Spiritual Thinking * Dynamic Face Recognition Comparison System 1. Portrait Information Resource Management The current authorities have established a population information system, a rental housing and floating population information system (residence permit system), an intelligence system, a police system, an escaped personnel system, and a tourism industry. The system, exit and entry management system, etc., have a large number of basic information and photographs of the personnel. Therefore, according to the basic information and photographs of the permanent population, floating population, key personnel, and fugitives, a corresponding database of portrait bases may be established for the purpose of carrying out the intelligent identification of portraits. Business applications, deepening the management of the public security of portraits, precision crime prevention and intelligence analysis, and providing data support. 
Second, the identity check, clean-up construction for household registration and identity information check, verify, clean-up services, find multiple identity personnel. Retrieval mainly refers to the retrieval of a large number of demographic identification information to find out whether there are “identities of different people†and “different people with the same status†in order to assist the demographic business department in data rectification and rectification. Based on the constructed database of portrait information, through N: N check and comparison, one-time completion of the inventory data of the resident population is compared, and non-single identity photo comparison information is generated. On this basis, further inventory is performed. The historical issues such as the quality of document information and photo data are comprehensively arranged and cleaned up. 
Shensi Airport Face Recognition and Matching System III. The dispatch and control personnel monitored and detected real-time monitoring of in-flights, case-related personnel, and blacklisted personnel, and built a real-time video-based real-time capture photo comparison and detection service, realizing the real-time alarm of dispatching personnel. A large number of video monitoring terminals have been established in major urban arterial roads, key management areas, and public places. Through the analysis and processing of various types of video information in the arterial bay entrances, key supervision areas, and public places, video capture and capture of captured portrait information has been provided. , At the same time, it is compared with the real-time alerting and control image database, and real-time alarms are compared with the portraits.
