This document describes an attendance management system that uses face detection. The proposed system would take pictures of students in a class using a high-definition camera and compare the faces to images stored in a database to automatically mark attendance. It discusses implementing this using OpenCV for face detection algorithms like Haar cascade and detecting faces in real-time. The system aims to eliminate proxy attendance and save time compared to traditional manual methods. It also lists some advantages and limitations of the proposed face detection-based attendance system.
