This document describes a camera-based classroom attendance system project. The objectives are to take attendance of a classroom using webcams and develop a hardware/software interface. The design methodology involves taking pictures of the classroom with webcams and analyzing them using OpenCV image processing software. The method divides the classroom into parts with one webcam for each, takes photos at intervals, converts them to grayscale, generates student masks, and subtracts photos to identify students based on face outlines. Requirements include suitable illumination and students sitting in the same places. Samples of implementation results are also shown.
