I used the one of face recognition tutorial by Pyimage Search . In which opencv frontal face xml is used crop the face and encode the facial features in 128 vectors and train and store it in a pickle file and use it compare with the input faces.
I use 20 images for each face

A face recognition attendance system uses facial recognition technology to automatically identify and verify individuals and check liveness. Fingerprint scanning systems are almost the norm for attendance systems, but the pandemic has raised the question of systems requiring physical touch. A face recognition attendance system is a contactless technology that eliminates any physical touch between man and machine. Knowing how the technology works makes it much simpler to comprehend how facial recognition attendance systems may make buildings and premises safer and more efficient even for face recognition car security.

Face recognition attendance systems are not reliant on a small number of facial characteristics; rather, they are very resilient and recognize a face based on several data points. Consequently, these systems can screen for face masks and identify individuals without removing the mask or altering facial characteristics such as beard, glasses, etc. The fact that personnel do not need to remove their masks is a significant advantage over other biometric systems. Modern attendance systems include very accurate face recognition algorithms that can also detect changes in facial characteristics such as spectacles, beards, etc. There are lots of top facial recognition software companies that employ facial biometric authentication and flutter real time face recognition for liveness check Kubernetes. Check out the list of facial recognition companies for liveness check face recognition and face liveness detection python.

By reducing physical contact in public and work spaces, pandemics like as Covid 19 may be effectively handled. There has been a huge surge in demand for the use of contactless technology since the epidemic. The industry has realized the advantages of face recognition and the use of attendance systems. Workplaces and multi-tenant workplaces may significantly minimize the frequency of interaction between persons, hence reducing the danger of viral transmission.

Attendance of students in a large classroom is hard to be handled by the traditional system, as it is time-consuming and has a high probability of error during the process of inputting data into the computer. This paper proposed automated attendance marking system using face recognition technique. The system deployed Haar cascade to find the positive and negative of the face and eigenface algorithm for face recognition by using python programming and OpenCV library. The proposed method using PCA to resolved the problems such as lightning of the images, noise from the camera, and the direction of the student faces. The attendance of the student was updated to the Excel sheet after student's face has been recognized.

The Smart Attendance System Using Face Recognition is a software application that automates attendance-taking using facial recognition technology. It eliminates the need for manual attendance-taking, which is time-consuming and prone to errors. This system enables the recognition of a person's identity using a camera and compares it with the database to record attendance.

We are building a Smart Attendance System Using Face Recognition that can automatically take attendance using facial recognition technology. The system will use a camera to capture the face of each person and match it with the database to identify them. The system will store attendance records for each person in an Excel file and generates a report.

We will build this face detection attendance system using Python programming language and facial recognition technology. We will use the OpenCV library to capture images from a webcam, detect faces, and extract facial features. We will then use the face_recognition library to recognize faces and compare them with the database to identify people. Finally, we will store the attendance records in a database and generate reports using NumPy.

The overall method combines several computer vision and deep learning techniques to perform real-time face recognition and attendance marking. It uses OpenCV's face detection algorithm and a pre-trained deep learning model for face recognition. The attendance log is stored in JSON format for easy access and manipulation. The code provides a user-friendly interface by displaying the video stream with the recognized names of individuals and a bounding box around their faces.

The entire process is automated and requires minimal manual intervention. By using face recognition technology, the system can accurately recognize individuals and mark their attendance, reducing the chances of errors or malpractices. It is a reliable and efficient way of managing attendance in various settings.

The deep learning algorithm that is were using for the smart Attendance Management System is the face recognition model. This model uses a deep convolutional neural network (CNN) to extract features from facial images and learn to map these features to a unique embedding vector for each individual.

The model is trained on a large dataset of facial images using a supervised learning approach, where it learns to minimize the difference between the predicted embedding vector and the true identity of the individual. The pre-trained face recognition model used in the above code is based on the ResNet architecture and has been trained on a large-scale face recognition dataset called VGGFace2.

In this section, we will focus on how to store the face embeddings generated by the face recognition model. Face embeddings are a compact numerical representation of a face that can be used to compare and recognize faces.

This code loads the images from the "dataset" directory, computes the face embeddings using the face_recognition library, and stores them in a directory called "embeddings" in a text file named "embeddings.txt".

The cv2 library is used for capturing video frames from the camera, the face_recognition library is used for face detection and recognition, the numpy library is used for scientific computing, the os library is used for working with directories, the json library is used for reading and writing data in JSON format, and the datetime library is used for recording the date and time of attendance.

This code block is the heart of the attendance system. It captures frames from the camera, detects faces in the frames, compares the detected faces with the precomputed embeddings and marks the attendance of the recognized faces.

The face_recognition.compare_faces() function compares the embeddings of the detected faces with the precomputed embeddings and returns a list of boolean values indicating whether each detected face matches any of the precomputed embeddings.

Overall, this code block performs real-time face recognition and attendance marking by detecting faces, comparing them with the precomputed embeddings, and adding new entries to the attendance log if necessary.

Line 15 uses face_recognition.face_locations() to detect the locations of faces in each image. The function returns a list of four-element tuples, one tuple for each detected face. The four elements per tuple provide the four coordinates of a box that could surround the detected face. Such a box is also known as a bounding box.

In this section, you created the encode_known_faces() function, which loads your training images, finds the faces within the images, and then creates a dictionary containing the two lists that you created with each image.

Recall that at the end of the last snippet, you added a test call to recognize_faces() with the parameter "unknown.jpg". If you use that image, then running detector.py should give you output like this:

Next, you draw another rectangle, but for this one, you define the rectangle with the bounding box coordinates that you got in the previous line. You also color in the rectangle by using the fill parameter. This second rectangle serves as the caption area directly under the bounding box that surrounds the recognized face.

After you define _display_face(), your recognize_faces() function is complete. You just wrote the backbone of your project, which takes an image with an unknown face, gets its encoding, checks that against all the encodings made during the training process, and then returns the most likely match for it.

In line 6, you open the validation/ directory with pathlib.Path and then use .rglob() to get all the files in that directory. You confirm that the resource is a file in line 7. Then, in lines 8 to 10, you call the recognize_faces() function from step three on the current image file.

PT. Restu Agung Narogong is a company with a total of 176 employees, queues often occur in the attendance process, both incoming and outgoing attendance. The employee needs to register their attendance. It is time consuming during the shift change. Therefore, a biometric system is needed to support the attendance system to identify employee without registering themselves. One of the alternative biometric systems is face recognition by using a computer vision. The purpose is to implement a crowd face detection with Raspberry Pi using the Naïve Bayes classifier. This system uses an algorithm to extract facial characteristics into mathematical data. Then the data is compared with data from other facial characteristics collected in the database. This device uses Python as a programming language with some of the scientific Python libraries. The testing of the Naïve Bayes method was conducted using a sample of dataset of 370 augmented facial imagery. The accuracy of this implementation is 76.31%, the precision is 78.25% and recall 81.25%. The background and lighting of the captured image affect the accuracy of this device.
