Globally, the presence of biometrics is highly approachable to fix any hurdle and irrelevant input and make a secure and tangible environment. Indeed biometrics helps you tremendously. You can manage everything on your basis to compete in the market. Especially for the attendance services in any organization, office, and building, it is the most important thing to record the presence of someone.
In today’s digital age, face recognition is beneficial and one of the most advanced biometric systems in the market. It plays a sophisticated or cumulative role that enhances a company environment toward logistic dimensions, especially for work areas that require attendance veriļ¬cation. Facial recognition is beneficial in verifying attendance to speed up the process of recording and verifying the person.
Day by day, the implementation is highly incrementing, and a simple biometric is now getting placed as a facial recognition system. This advanced artificial input working without contact with humans and detecting them in the workplace makes a safe, responsible, and compatible output.
A facial recognition system is an advanced artificial intelligence
The system is now digitalized and moving with tremendous mechanization. The world is now more active in developing its economic power and using advanced methods to stimulate its business quickly. Here, attendance is much beneficial for any organization to manage their employee to know about their activities and working period, which increase the company's productivity.
Intrinsically, facial recognition is an advanced biometric system that terminates an obsolete mindset of maintaining the system and replacing it with an ample opportunity for time, safety, and accountability. It works with a diversified process and detects an individual systematically by the camera, images, CNN-classifier, comparison/identification, and recognition/verification. And all these processes will work on the Haar cascade classifier. Haar Cascade is a feature-based object detection algorithm used to detect and identify objects in real-time images (Paul Viola and Michael Jones). A cascade function is trained on many positive and negative images for detection. Para vision research indicates that facial recognition models trained on the actual face are good at understanding “hidden information about synthetic faces.”
Research shows that It plays a crucial role in recognition. It conveys people’s identity and thus can be a key for security solutions in many organizations. The facial recognition system is increasingly trending globally as an extraordinarily safe and reliable security technology. It is gaining significant importance and attention from thousands of corporate and government organizations because of its high level of security and reliability.
The system captures biometric measurements of a person from a specific distance without interacting with the person. This technique is based on the ability to recognize a human face and then compare the different features of the face with previously recorded faces. This feature also increases the importance of the system and enables it to be widely used worldwide. It is developed with user-friendly features and operations that include different nodal points of the face.
How algorithm work with Face Recognition
In recent times, artificial intelligence has been developing rapidly. We know it is highly advanced, provides self-services with less human involvement, and take place in a supermarket. Artificial intelligence is closely linked to computer vision. Things are working in artificial intelligence with algorithms. The algorithm is a rule based on a specific neural network that detects face landmarks and distinguishes faces. The detecting part of human facial features like eyes, nose, mouth, etc.
The function of facial recognition relies on an algorithm, which would work with a generating database. There are various processes below through which you can analyze the proper operation of the facial system.
Adding the image to the database
Get the image
Get the Face detector object
Apply the Face detector object to the image to extract the features of the detected face
Add the image to the database
Comparing the input image with the database of images
Get the image
Get the face recognition machine
Apply the Face detector to the image and extract the features.
Compare the image with the database
Verification or denied
There are several faces that we have seen, and also machines get, but all the faces are slightly different. Therefore face recognition system recognizes all the faces in the workplace after getting images in real-time or 3d and saving them in the database in code form. At the time of recognition, the input images are compared with the database. Here, the input image is called the probe, and the database is called the gallery. Then it gives a match report.
Features base approaches for the facial recognition system
According to various research, there are three approaches to face recognition;
Feature base approach: In the feature-based method, the local features like nose and eyes are segmented and can be used as input data in face detection to easier the face recognition task. In other words, the Feature-based approach identifies the separate sections of any face.
Holistic approach: Overall, the face would be detected as the input for face recognition.
Hybrid approach: Hybrid approach is a combination of feature-based and holistic approaches. This approach is local, and the whole face is used as the input to the face detection system.
Conclusion
A Biometric system is highly suitable and legitimises working behaviors. The facial recognition model of a biometric system is highly advanced, and get involved artificial intelligence that helps to grow and make a good environment. Face recognition system is one of the most intensive technologies in computer vision, with new approaches and encouraging results reported every year. It is putting their work with various techniques and methods and mechanizing it with a productive environment.
