The Design And Implementation Of The Mobile-police Face Recognition Retrieval And Alignment System

With the development of science and technology and progress, face recognitiontechnology has been gradually applied to the retrieval ratio of police actual combat,plays a more and more important role in the rapid verification unidentified personstrue identity work. The actual application needs therefore to develop in line with theactual public security work of our city police face recognition and retrievalcomparison system more urgent, the successful development of this system canprovide strong technical support service policing and social management.This paper reviews the current face recognition algorithms at home and abroad,focuses on local feature analysis, multi template matching, extraction, importanttexture feature space nonlinear mapping, linear discriminant analysis, face recognitiontechnology. The system user demand analysis, the functional requirements, systembusiness processes and use case analysis; finished the system design, database designand function design, system mainly include face feature database management, facerecognition, information query, data statistics, system management and otherfunctional modules. In the actual development process, combined with the gender, ageand personnel face features such as public security elements, including theestablishment of the fugitives, illegal crime personnel, temporary dispatchedpersonnel500000face integrated database in advance, developed a se t of using BSstructure, using C#programming language, ORACLE database system databasestructures, face recognition to meet the actual needs of our city public security workretrieval matching system, and will be seamless docking with the Tianjin publicsecurity police mobile wireless terminal.The system user friendly interface and convenient operation, the use of "frontlinelaw enforcement police can easily police" terminal shoot suspects photos, and in ashort time in the photos, feature extraction, matching, retrieval result and a series ofoperation process. Fast and efficient to solve the policemen in the patrol, home visits,safety inspection, emergency and other daily police work for fast verification offugitives, illegal crime personnel, temporary dispatched personnel, have certainapplication value in our city police actual combat.
