A real-time face recognition based on mobileNetV2 model

Facial recognition technology is one of the fastest developing technologies. Thanks to its efficacy, ease of use, and extensive applications in health, protection, and surveillance, face recognition is the most widespread technology compared to other biometric ones. Technologies based on deep learning and neural networks have demonstrated superior efficiency and speed when compared to traditional approaches for recognizing persons. In this work, we propose a fast real-time facial recognition system that is applicable for mobile devices and devices of low computational power. It relies on today's latest convolution neural networks algorithms. The database is built based on photos from a collection of known people and some VggFace dataset celebrities. The proposed system is divided into several steps, starting with the detection of faces in the input images using the MTCNN algorithm, followed by their alignment and preprocessing, extracting the face characteristic vectors for each face using the mobileNetV2 model, and finally comparing, classifying and distinguishing the faces. The performance of the system has been evaluated using some examples. The system produced results with an accuracy of 92.67%, with an average of 11.68 frames per second. When compared to the state-of-art models, the experimental results demonstrated that mobilenetv2 model was 2 times faster than ResNet50 model and 4 times faster than VGG16.
