A Face Verification System on Mobile Terminal Based on Depth Learning

作为一种新兴的身份验证技术,人脸验证广泛应用于门禁、考勤等需要身份验证的场合。本文综合考虑移动端人脸验证的需求与生产环境,以及现有人脸验证算法的效率和可移植性,设计并实现一种基于安卓系统平台的人脸验证系统。该系统能够离线部署于搭载安卓系统的移动端设备,通过摄像头获取人脸图像并在本地进行图像的数据处理完成人脸验证工作。在算法上,该系统采用深度卷积神经网络进行图像处理与人脸特征向量提取以提高人脸验证的准确率。在实现上,通过联合编译Java和C++代码提高算法运行效率以适应深度学习算法在移动端的应用。实验表明,本系统能够在确保准确率高达97.16%的前提下快速完成人脸验证流程,基本满足工业化应用需求。

As a new authentication technology,face verification is widely used in access control,attendance and other needs of the occasion of authentication. This paper designs and implements a face verification system based on the Android system platform,taking into account the requirements and production environment of mobile face verification and the efficiency and portability of existing face verification algorithms. The system can be deployed off-line in the mobile device equipped with Android system,through the camera obtaining a face image and the local image processing data to complete face verification work. In the algorithm,the system uses deep convolution neural network for image processing and face feature vector extraction to improve the accuracy of face verification. In the implementation,through the joint compiler Java and C ＋ ＋ codes improving the efficiency of the algorithm to adapt to the depth learning algorithms in the mobile side of the application. Experiments show that the system can quickly ensure the accuracy rate of 97. 16% under the premise of rapid completion of the face verification process,basically meet the needs of industrial applications.
