Abstract - This paper introduces a new method in
attendance management systems using computer vision
algorithms. We propose the system using real time face
detection algorithms using dlib library and cognitive face ,
which automatically detects and takes students attendingona
lecture. The system representsa toolforinstructors,combining
algorithms used in machine learning with adaptive methods
used to track facial expressions during a longer period of time.
This new system aims to more efficient than traditional
methods,at the same time being nonintrusiveandnotinterfere
with the regular teaching process. This approach promises to
offer accurate results and a more detailed attendance
reporting system which showsstudent activity andattendance
in a classroom.

1.INTRODUCTION
A key factor of increasing the quality of education is
having more number of students attend classes regularly.
Students are stimulated to attend classes using attendance
points which at the end of a semester constitute a part of a
students final grade. However, this presentsadditionalwork
on teachers, who must ensure to correctly mark attending
students, which also wastes a considerable amount of time
from the teaching process. The task would get further
complicated if one has to deal with large groups of students.
This paper introduces a new attendance management
system, without any collision with the regular teaching
process. The system can beusedalsoduringexamsessionsor
other teachingactivities where attendanceisobligatory.This
system eliminates classical student identification such as
calling student names, or checking respective identification
cards, which can interfere with the teaching process.
In this paper we aim to build an Attendance management
system with the help of facial recognition owing tothe
difficulty in the manual way of taking attendance.
The overall objective is to develop an automated class
attendance management system comprising of a desktop
application working in conjunction with a mobile
application to perform the following tasks:
• To detect faces real time.
• To recognize the detected faces by the use of a suitable
algorithm.
• To update the class attendance register after a successful
match.
• To design an architecture that constitutes the various
components working harmoniously.

LMS systems such as Angel require students to login in to a
web page with a special one time temporary key so as to
mark their presence on class. The problem with these
approachesisthattheycollidewiththeconventionalteaching

companies, that implement face recognition in work
environments. Kawaguchi proposes face recognition in

Related systems that use lifescience(fingerprintrecognition,
iris recognition etc) to identify users square measure time
management systems used in several establishments.
However, putting in these systems in each schoolroom in a
very university would pose an even bigger monetaryburden.
it'd additionally require from the university to record
biometric information from all students, which might

introduce additional privacy issues. These systems also are
subject to physical injury from their users. so they have
further maintenance prices. the thought projected by
America, removes physical accessfromanyonetothesystem.
A Survey by Muhammad Sharif1 , Farah Naz1 , Mussarat
Yasmin1 , Muhammad Alyas Shahid says that they deduced
Face recognition has gained a significant position among
most commonly used applications of image processing
furthermore availability of viable technologies in this field
have contributed a great deal to it. In spite of rapid progress
in this field it still has to overcome various challenges like
Aging, Partial Occlusion, and Facial Expressions etc affecting
the performance of the system, are covered in first part of
the survey. This part also highlights the most commonly
used databases, available as a standard for face recognition
tests. AT & T, AR Database, FERET, ORL and Yale Database
have been outlined here. While in the second part of this
survey a detailed overview of some important existing
methods which are used to dealing the issues of face
recognition have been presented.
3.GENERAL IDEA
This projected system introduces a replacement
automatic group attendance action marking sysem, which
integrates pc vision and face recognition algorithms into the
method of group action attendancemanagement.Thesystem
is enforced employing a non intrusive camera put in on a
classroom, that scans the space, detects and extracts all faces
from the no heritable pictures. After faces are extracted,
they're compared with associate existing information of
student pictures and upon no-hitrecognitionastudentgroup
action list is generated and saved on the database.Thispaper
addresses issues like real time face detection on
environments with multiple objects, face recognition
algorithms furthermore as social and pedagogical problems
with the applied techniques.
4.SYSTEM ARCHITECTURE
Fig-1: System Architecture
The system architecture consists of three modules
 Capturing the image
 Image pre-processing(Feature extraction)
 Face detection
 Face recognition
The entire process is described in the flowchart shown in
figure 2
Fig-2: System Architecture flowchart
The system architecture is as shown in Figure 1. The
proposed automated attendance management system is
based on face recognition algorithm. A image is captured at
random time covering the entire classroom and then fed to
the system. Face region is thenextractedandpre-processed
for further processing.. Face Recognition proves to be
advantageous than other systems. When the student’s face
is recognized it is fed to post-processing. The System
algorithm is discussed. The stages in the proposed
Automated Attendance Management System are as shown
in the Figure 1
4.1 IMAGE CAPTURE
The camera takes pictures of the entire classroom at the
given intervals. The process would continue until all faces
are detected successfully or unless told to stop by admin.
The captured image is then sent to server using web
services for processing.
4.2 FACE DETECTION
Face detection algorithms are processor intensive, so the
server based tool is used. Face detection is a part of object
detection but here the subject of interest are faces. Many
factors affect the efficiency of face detection algorithms.
Factors like pose, position, light , rotation.
The face detection process from still images can be
divided into several steps. There are several face detection
algorithms that can detect multiple faces. Most students face
towards front of the classroom, so the system presenteduses
dlib library for face detection.
The classifier works by coaching a model exploitation
positive face pictures and negative face pictures. A positive
image is a picture that contains the required object to be

detected, in our case this object could be a face. A negative
image is a picture that doesn't contain the required object.
when the model is trained, it's able to establish face options,
that is later hold on on a XML file. A problem long-faced
throughout this method was the massive variety of false-
positives: objects erroneously detected as faces. This wasn't
such an enormous issue for United States, since a false-
positive doesn't end in a identification throughout the
popularity section. thanks to this, we have a tendency to
down the detection threshold, therefore all faces maywellbe
detected. After a face has been detected, the parallelogram
intromission this face is cropped and processed later by the
face recognition module. This parallelogram represents one
face, and when being cropped as a picture is transferred on
server. every file transferredisrenamedtopossessasingular
ID. The face detector in action is shown in Figure 3 , faces
identified are enclosed in green rectangular boxes .

4.3 FACE RECOGNITION
Face recognition means identifyinga face from a groupof
faces in database. Our college, during course registration
captures images and stores them in a database.
Since our system is setup to capture solely frontal pictures
the cause of the face in not a difficulty. once a face is
captured throughout the face detection part, it's reborn into
grey scale. an equivalent conversion is applied to faces on
our student image information. we tend to conjointly do
background subtraction on our pictures thus alternative
objects don't interferethroughoutthemethod.Anotherissue
is that faces ar subject of modification throughout time
(facial hair, eyeglasses etc). Whenever we tend to with
success determine a face, a duplicate of that face is keep
within the information of faces for that student.atthesideof
the image we tend to store the time and date once thisimage
was taken. This way though a student step by step changes
his look (e.g., grows a beard) the system continues to be
capable to spot him, since it's multiple pictures of an
equivalent person. On every resultant scan for a student, the
popularity module starts examination pictures from this
information, sorted by date in degressive order. This
approach was chosen since the newest image ofa studenton
our information is possibly to be additional almost like this
captured image. Of course, a forceful modification on a
student’s look causes the system to not determine that
individual student. to resolve this issue,we'vegotencloseda
module, that lists all unidentified faces and also the teacher
is in a position to manually connect a captured face with a
student from the list. This image is additionally keep on our
information, as associate updated image of this explicit
student. This manual recognition method is performed just
the once. in a very sequent scan, this student is known
mechanically by our system. To speed up the face
recognition method we tend to solely compare pictures
captured in a very room, with the information of scholars
listed for that course solely. This ensures that we tend to
method solely low set of pictures offered on our server.
5. CONCLUSIONS
It can be concluded that a reliable, secure, fast and an
efficient class attendance management system will be
developed replacing a manual and unreliable system. This
face detection and recognition system will save time, reduce
the amount of work done by the administration and replace
the stationery material currentlyinusewithalreadyexistent
electronic equipment.
There is no need for specialized hardware for installing the
system as it only uses a computer and a camera. The camera
plays a crucial role in the working of the system hence the
image quality and performance of the camera in real time
scenario must be tested especially if the system is operated
from a live camera feed.
The system can also be used in permission based systems
and secure access authentication (restricted facilities) for
access management, home video surveillance systems for
personal security or law enforcement.
