Modern Problems of Face Recognition Systems and Ways of Solving Them

Abstract

Currently, the face recognition system is applied in various fields such as classified materials, file transferring, and general human interaction and innovative technologies, including cell phones with owner recognition function. The relevance of this research lies in the need to consider problems touching upon the increase in the efficiency of such technologies. The objective of this study was to improve the algorithm of the face identification system from different sides in order to demonstrate appropriate results. In the course of the study, a method based upon deep neural networks was applied through the projection of layers. As a result, a receiver operating characteristic curve was constructed to evaluate the quality of binary classification, and loss functions for deep learning, data distribution, and algorithm accuracy were demonstrated. Proceeding from the results obtained, it was found that the selected face identification system is resistant to each of the influencing factors (make-up, lighting, posture, etc.) considered separately in the work. The operation principle represents an original technical solution for face recognition problems when images in the database have discrepancies, which is a typical scenario in the actual world. The testing accuracy in this work reaches 95.04%.
