Attendance and Security Assurance using Image Processing

In Maximum number of educational institutions we can see prevailing system of attendance where attendance of students are taken manually by the professors calling out the names of the students. In some universities we can find RFID system present for attendance. The manual system of attendance is very time consuming and may not be much efficient as well. Whereas RFID based attendance is also not much reliable as we don't know if the RFID card is actually used by the student whom it belongs or not. Both existing techniques for attendance system have problems in it. So our paper has used Image Processing techniques and automated the attendance system where the attendance is taken by the system by recognizing the faces of the students. The system has dataset of known faces or students such that when any unknown face detected inside the classroom, he/she will be recognized as an intruder. This will safeguard the students from any kind of invasion or attack. In this paper we have discussed the techniques which can be used to implement image processing for automating the attendance system and assure security of the students.

I. INTRODUCTION

With new technologies being developed, manual attendance system has been replaced by RFID based attendance in few colleges and universities. But in most educational institutions we can find manual method existing. Manual attendance is taken by using attendance sheet by the faculty member or professor in the class. This method is very monotonous and time consuming. Manually recorded attendance is easy to manipulate. Moreover, it is very difficult to verify one by one student in classroom environment which results the attendance not to be completely accurate. There exist chances of absent student to be marked present and vice versa. RFID based attendance system can turn out to be expensive to implement. Also, the RFID card marks attendance present which means in the case of absence of student if the card is somehow present then the student is also marked present. So, the result of RFID is also not completely reliable.
