A Flexible Approach for Automatic Door Lock Using Face Recognition

The model of smart door lock using face recognition based on hardware is the Jetson TX2 embedded computer proposed in this paper. In order to recognize the faces, face detection is a very important step. This paper studies and evaluates two methods of face detection, namely Histograms of Oriented Gradients (HOG) method which represents the approach using facial features and Multi-task Cascaded Convolutional Neural Networks method (MTCNN) represents using of deep learning and neural networks. To evaluate these two methods, the experimental model is used to verify the hardware platform, which is the Jetson TX2 embedded computer. The face angle parameter is used to rate the detection level and accuracy for each method. In addition, the experimental model also evaluates the speed of face detection from the camera of these methods. Experimental results show that the average time for face detection by HOG and MTCNN method are respectively 0.16s and 0.58s. For face-to-face frames, both methods detect very well with an accuracy rate of 100\%. However, with various face angles of 30o, 60o, 90o, the MTCNN method gives more accurate results, which is also consistent with published studies. The smart door lock model uses the MTCNN face detection method combined with the Facenet algorithm along with a data set of 200 images for 1 face with accuracy of 99\%.
