Abstract - The attendance system was created to ensure the decorum and discipline of the school, colleges, and universities.
There are a variety of traditional methods for recording student attendance in a class. The first is to call the roll number, and the
second is to have pupils sign a sheet of paper next to their roll number. As a result, it was necessary to evolve this system in order
for it to become more user friendly, less time-consuming, and efficient. This is a visual attendance system designed to help
professors take attendance of the entire class without causinganydisruptionorwastingtime. Thisvisualattendancesystem canbe
used in any field that requires regular attendance. In addition, as the project objectives and the designcriteriaallmet, it’sgreatest
to say this project is an engineering solution for all university and colleges to track and manage the attendance.
Key Words: Attendance, face identification, Recognizer, OpenCV
1. INTRODUCTION
Students' attendance is traditionally taken manually using an attendance sheet provided by a faculty member in class.
Traditional systems were more prone to proxies, blunders, and errors. The more effective the attendance system, the higher
the level of involvement and learning in class. Previously, we used tactics such as roll numbering, calling, and signingagainsta
specific roll number. Furthermore, in a largeclassroomenvironmentwithdistributed branches,itisextremelydifficulttocheck
whether or not authenticated students are replying one by one. Image processing has led to the development of facial
recognition systems. Image processing is concerned with the extraction of necessary data from a digital image, and it plays a
unique role in technological growth.
It is also feasible to detect if a student is sleeping or awake during a lecture, and it can be used to ensure a student's presence
during exam sessions. The presence of students may be determined by capturingtheirfacesona high-definitionmonitorvideo
streaming service, making it extremely dependable for the computer to recognise all of thepupilsintheclassroom. Forfeature
detection, the system employs a variety of methods, including image contrasts,integral pictures,colour features,anda cascade
classifier.
The system is evaluated in a variety of lighting settings, with diverse facial expressions, partial
faces (in densely filled classes), and beards and spectacles present or absent. In the majority of the cases studied, improved
accuracy (almost 100 percent) is reached. Large data sets and complex features are required for face recognition in order to
uniquely identify various persons by adjusting different obstacles such as illumination, stance, and age. Facial recognition
technologies have improved significantly during the last few years. In the recent decade, there has been a tremendous
advancement in the field of facial recognition. Most facial recognition systems now work effectivelywithonlya few facesin the
picture. Furthermore, these methods have been tested under regulated lighting settings, with good face positions and photos
that are not fuzzy. The system that is proposed for face recognition in this paper for attendance system is able to recognize
multiple faces in a frame without any control on illumination, position of face.
Computers may also be programmed to identify the individuality of faces, so we must programme or train themachinehowto
distinguish between faces based on their distinguishing characteristics. As seen below, facial recognition can be split into two
categories:
1.) Verification
2.) Identification
Verification is a one-on-one matching process (match or no match). The tool may be used to lock and unlock systems,phones,
and other electronic devices.
Identification is a technique for distinguishing an individual within a group of individuals, such as one out of N.

Face Detection and Recognition Using Skin Color [3]. Face detection performance using skin color division and a thresholding
skin colour model paired with the AdaBoost algorithm. Principal Component Analysis (PCA) and K-Nearest Neighbor (KNN)
based categorization are used to extract the facial attributes. Morphological Operators were also applied to increase the face
detection performance. There is no suitable face orientation, image illumination is poor, and thedistancebetweenthefaces and
the camera is variable in some photographs for which the expected results have not been achieved. Only a few photos with a
significant level of orientation variation are correctly spotted and recognized. This results in a database recognition rate of
roughly 96 percent.
Shireesha Chintalapati, M.V. Raghunadh, andcolleagues[4]identifiedthevariousstrategiesforimplementingafacerecognition-
based attendance monitoring system. There are two sections of the process. The face detection method is the first, and the face
recognition method is the second. The ViolaJones face detection algorithm uses four important components to recognise faces:
Haar features, integral graphics, Adaboost algorithm, and cascade function. Face recognition can be included using LBP (local
binary patterns). LBP is a tool for converting images into machine-readable forms like binary. To make the calculation more
straightforward, The discovered image should be converted to greyscale until facial detection and identification can be
performed. Face recognition takes a snapshot of an image (student dataset)and then searches forfacesinthephotos,whichare
then saved for future use.
The principal function is thatthe image's features make it simple to locatethe image's boundaries or lines, or to selectlocations
where the pixel intensities abruptly change. The haar featuremovesfromthetoplefttothebottomrightoftheimage,lookingfor
a specific characteristic that indicates edges traversing. Edge feature-based techniques have the advantage of integrating
structural information by grouping pixels of face edge maps toline segments. After comparing the pixel computations, the next
step was completed.

privacy concerns. These systems can potentially be damaged physically by their users. As a result, they will incur increased
maintenance costs. The concept we offer denies anyone physical access to the automated system
3. METHODOLOGY
We will build a viable solution to our problem based on the literature survey, since we have thoroughly investigated many
areas that are directly related to our project. In this section, we will present a method that will provide an overview of our
project's approach and how it should be carried out. Becausetheprioreffort wasinsufficient,wedecidedtobuildthisprojectin
the most viable and efficient manner possible. RetinaFace and Arcnet algorithms for face recognition and verification are the
proposed face detection modules for this project.

4. MODELS
RetinaFace- A deep convolutional network is used by RetinaFace. The Zeiler&Fergus [5] style networks and the more
contemporary Inception [6] type networks are discussed. The most significant component of our method, given the model
details and treating it as a black box, is end-to-end learning of the entire system. To do this, we use the triplet loss, which
precisely represents our goals in face verification, recognition, and clustering. Specifically, we aim for an embedding f(x)from
an image x into a feature space R d such that the squared distance between all faces of the same identity, regardlessofimaging
settings, is minimal, and the squared distance between two face pictures from different identities is big. RetinaFace learns a
direct mapping from face images to a compact Euclideanspaceinwhichdistancesare directlyproportional toa measureofface
similarity. Tasks like face recognition, verification,andclusteringmaybeeasilyimplementedusingtraditional approacheswith
RetinaFace embeddings as feature vectors after this space has been created.
Arcface- ArcFace is a machine learning model that takes two face photos as input and outputs the distance between them to
determine how similar they are. It may be used to recogniseandsearchforfaces.ByreplacingSoftmaxLosswithAngularMargin
Loss, ArcFace provides a similarity learning method that allows distance metric learning to be solved in the classification
challenge. The cosinedistance, which is a method utilisedby search engines and may be determinedbytheinnerproductoftwo
normalised vectors, is used to calculate the distance between faces. If the two vectors are equal, θ and cosθ=1 will be returned.
They will be π/2 and cosθ=0 if they are orthogonal. As a result, it can be used as a comparison measure.

Figure 3. The Triplet Loss minimizes the distance between an anchor and a positive, both of which have the same
identity, and maximizes the distance between the anchor and a negative of a different identity
Firstly we create a database of students that we have to have to attendance , then taking the image of students present in the
class using the RetinaFace algorithm[7] and identifying those images by using the Arcface algorithm[8]. This whole processis
based on a web application and very helpful for organizations.
We choose the Automated Attendance Monitoring System project after considering the demandsofsociety'sday-to-dayneeds
and wants. As technology advances, we are more likely to think outside the box and come up with a game-changing concept.
Education is the most important thing that everyone should obtain because it provides the foundationfora betterlifestyleand
will undoubtedly improve a community's level of living. Our educational system is lacking in student involvement in schools,
colleges, and universities.
Face-to-face security systems are currently being used in sectors like identity protection and banking, although mostly
in conjunction with other existing solutions like fingerprint or SMS verification. However, over the next year or two,
we'll see large multinational corporations use increasingly sophisticated facial biometrics and AI-driven technology to
improve their security capabilities and better protect customers from identity fraud and data loss.
