Design of Energy Efficient System for Classrooms Using Face Recognition

Abstract

A novel face recognition based door access system was implemented to use in classrooms. This system uses a ARM7 with webcam to capture and process digital pictures of the students and recognize the faces to open the door, and automatically switch on the lights and fans based on number of students. The entire system uses two cameras with two GUI apps one for entry and one for exit. The algorithm runs continuously and detects registered faces and sends it to the microcontroller. Based on received data microcontroller open the door and also increments the number of students. If at exit side GUI detects the face then microcontroller decrements the number of students. The GUI designed especially for this system. The experimental results shows that the efficiency of this project is high when compared with IR based door access system.
