Background. The coronavirus pandemic (COVID-19) has led to a major global health crisis due to the rapid spread of the virus. The World Health Organization has provided guidelines for protection against this disease. One of the effective recommendations is to wear a medical mask in public or crowded places. Involving human resources to monitor how these requirements are met is ineffective. It is necessary to automate the process of determining a properly dressed medical mask in real time using a video camera. The authors have developed an application that effectively copes with this task. Objective. The purpose of thew paper is the application development of a medical mask recognition in real time using a video camera, adapted for the use in modern Ukrainian reality with high accuracy and low system requirements. Methods. Analysis of existing analogues in the world, building a model of convolutional neural network, the architecture of which will detect and classify the image obtained from the camcorder in real time, create application architecture, develop a model in Python programming language, application testing. Results. A convolutional neural network of its own architecture has been created. The use of the Adam algorithm to optimize learning and use binary cross entropy as a cost function is substantiated. The method of face recognition using Haar features has been improved. High rate of convolutional neural network training was obtained: the training set accuracy - 97.46%, the test set accuracy - 97.23%, the cost function value at the training set - 2.37%, the cost function value at the test set - 2.57%. An application consisting of three modules has been developed: a machine learning module, an image processing module, a video camera activation module and a mask recognition device. Conclusions. The application effectively copes with the task of recognizing the presence of a medical mask in real time. The developed model in comparison with the analogues has a smaller size and simpler architecture without compromising accuracy or speed. The software has been successfully tested on various operating systems and hardware configurations. The application can be used in areas where there is a need to automate the process of determining the presence and accuracy of wearing a medical mask in real time.
