The automated attendance system described in this article was created using the MATLAB programminglanguage. We want to build a "Automated Attendance System Based on Facial Recognition," which will be useful for a variety of purposes in a variety of settings. In order to accommodate the face authorization, the application includes face identification, which saves time while also eliminating the potential of proxy attendance. Therefore, this technologymay be employed in a situation when attendance is crucial. Built on the MATLAB platform, the system is easy to use. The Principal Component Analysis (PCA) approach, which is based on eigen faces, is used in the proposed system. This approach evaluates the test and training photos in order to identify which students are present and which students are not present on the test and training images. A record of attendance is maintained in an excel sheet that is automaticallyupdated by the system. Because it is time-consuming and has a high risk of error throughout the data-input process, the conventional system fails to manage student attendance in a large classroom. In this study, an automated attendance marking system based on face recognition was developed and shown.
