基于卷積神經(jīng)網(wǎng)絡的人臉識別系統(tǒng)設計與實現(xiàn)
[Abstract]:With the development of society, people's identity information becomes more and more important in production and life. Face recognition is not only a hot topic in computer vision, but also widely used in many fields such as security, finance, electronic government and so on. In this paper, the application of convolution neural network model in the deep learning method to face recognition in natural scene is studied. Compared with the traditional face recognition method, the model of deep convolution neural network does not need to design a relatively complex and time-consuming feature extraction algorithm, so we only need to select or design an effective neural network model. With a large number of training samples, the image features can be extracted and a relatively good classification accuracy can be obtained by a simple and efficient training. The performance and effect of this method mainly depend on the design of network structure, so in the research process of this paper, the emphasis is on how to build a reasonable network model. The related techniques are adopted to make the training set converge quickly and stably, and finally a good recognition effect is obtained. In this paper, the methods of face detection and face recognition are analyzed, optimized and realized. In the process of face detection, the Haar feature is combined with the Adaboost algorithm, and the method of integral graph is used to speed up the evaluation of Haar features, so that face detection can be realized quickly and efficiently. This module not only realizes the functions of static face detection and dynamic face detection, but also embeds face detection into face recognition system to improve the efficiency of face recognition. In the process of face recognition, by reasonably reducing the training parameters of the original VGG convolution neural network, the improved VGG network model is obtained, and the convergence time of the model is reduced by using a better parameter initialization method than the random initialization method. Finally, the new model not only solves the problems of high hardware requirement and difficult training of the original VGG model, but also successfully applies to face recognition in the natural environment, and carries on the experiment on the LFW (Labeled Faces in the Wild) face database after strict preprocessing. The accuracy rate is 92%. In this paper, a real-time face recognition system is implemented by applying the above model algorithm to the real-time scene. The function and flow of each module of the system are introduced in detail, and applied in the self-built face database, and the accuracy is 94%. The system verifies the effectiveness of this method and meets the requirements of face recognition.
