ABSTRACT

This research aims at providing a system to automatically record the students attendance during lecture hours in a hall or room using facial recognition technology instead of the traditional manual methods. The objective behind this research is to thoroughly study the field if pattern recognition (facial recognition) which is very important and is used in various applications like identification and detection.

1. Introduction 1.1 Background of the study The rapid development in the field of pattern recognition and its uses in different areas e.g. (signature recognition, facial recognition), arises the importance of the utilization of this technology in different areas in large organizations. This is mainly because these applications help the top-management take decisions that improve the performance and effectiveness of the organization. On the other hand, for an organization to be effective, it needs accurate and fast means of recording the performance of the people inside this organization. Biometric recognition has the potential to become an irreplaceable part of many identification systems used for evaluating the performance of those people working within the organization. Although biometric technologies are being applied in many fields it has not yet delivered its promise of guaranteeing automatic human recognition. This research is the first of its kind to attempt to provide an automated attendance system that recognizes students using face recognition technology through an image/video stream to record their attendance in lectures or sections and evaluating their performance accordingly. 1.2 Problem definition Every time a lecture or laboratory starts, the lecturer delays the lecture to record students attendance. This is a lengthy process and takes a lot of time and effort, especially if it is a lecture with a huge number of students. It also causes a lot of disturbance and interruption when an exam is held. Moreover the attendance sheet is subjected to damage and loss while being passed on between different students or teaching staff. And when the number of students enrolled in a certain course is huge, the lecturers tend to call a couple of student names at random which is not a fair student evaluation process either. Finally, these attendance records are used by the staff to monitor the students attendance rates. This process could be easy and effective with a small number of students but on the other hand, dealing with the records of a large number of students often leads to human errors.

1.3 Proposed scope and enhancement This project proposes solutions to all the above mentioned problems by providing an automated attendance system for all the students that attend a certain lecture, laboratory or exam at its specific time, thus saving time, effort and reducing distractions and disturbance. Another advantage concerning exams, is when the invigilator or the advisor accidentally loses an exam paper or the student lies about attending the exam, there will be a record of the students attendance for the exam at that time, thus protecting both lecturers and students rights. In addition, an automated performance evaluation would provide more accurate and reliable results avoiding human error.

2. Literature review and prior research I have studied the literature available in the fields of pattern recognition and biometric systems with a focus on facial recognition. In addition, a study of previous attendance systems and its atomization attempts was conducted to examine the similar previous systems. The literature is divided into two main parts; the first part examines the different biometric characteristics and systems. In the second part, an in-depth study on facial recognition is conducted for it is the technology to be used by our proposed project. 2.1 Biometric recognition: There are three different types of authentication: something you know, such as passwords, something you have, such as badges or cards, and finally something you are, which mainly depends on biometrics and physical traits. Each of these three authentication methods has its advantages and disadvantages, and each is considered appropriate for certain types of application. Among there three types, scientists and researchers consider biometric recognition systems as high-level security systems. They define the biometric term as the science, involving the statistical analysis of biological characteristics. Biometric recognition generally matches a live digital image of a portion from a certain physical body part with a previously recorded image of that same portion; whether it is in identification mode where one-to-many comparisons take place, or verification (authentication) mode where one-to-one comparisons occur. 2.1.1 Emergence For thousands of years, humans have used biometrics and physical characteristics such as face and voice to identify other human beings for a wide variety of purposes, ranging from simple business interactions to
