Design And Implementation Of Access Control System Based On Face Recognition Algorithm

With the improvement of information technology development and embedded, face recognition, computer network technology, people are feeling the convenience and benefits the technology brings.The system gets face image through the camera, in the background of application system to complete the image recognition, and then to the microcontroller to send commands to control the access control system. Software uses wavelet transform on face images are 2 wavelet decomposition, and then the discrete cosine transform of the low frequency components(DCT) feature extraction value, finally using Euclidean distance and nearest neighbor classifier. Using OpenCV face recognition algorithm for processing the output. To achieve the system structure is simple, convenient, fast recognition speed and high accuracy.This dissertation describes the design and implementation of face recognition algorithm based access control system. Based on the study of face recognition algorithms, the entire access control system further design and implementation of a detailed elaboration. The main contents are:1. Simply introduced the background, purpose and significance of this study, introduce the background of face recognition, expound the present situation of domestic and international recognition and difficulties of face recognition, the dissertation also introduce the related technology needs.2. The research of face recognition algorithm: This dissertation focuses on the Gabor algorithm, K-L algorithm, Haar feature extraction of the three feature extraction algorithm algorithm are introduced in detail, and compared with the elaboration and experiments on PCA and LDA these two kinds of face recognition algorithm.3. Design and implementation of access control system: Starting with all parts of the system model, the overall results, functional modules, database design are introduced from requirements analysis.4. System test: In recognition of the core algorithms have been the end of the design and implementation of a detailed study and after the entire access control system.This dissertation carried out a detailed test of system integration, and gives the functional test report and test report. Face recognition access control system based on this design, to some extent.
