This document proposes a face recognition-based mobile automatic classroom attendance management system that does not require any extra equipment. It uses a filtering system based on Euclidean distances calculated using three face recognition techniques (Eigenfaces, Fisherfaces, and Local Binary Pattern) for face recognition. The proposed system includes mobile applications for teachers, students, and parents to manage attendance in real-time. It was tested among students and produced satisfactory results. The system aims to make attendance taking more efficient and less prone to errors compared to traditional paper-based methods.
