Application for Student Attendance Based on Face Recognition

Facial recognition represents a system for automatic recognition or identification of persons based on digital pictures of their face. There are multiple algorithms that the recognition software uses but it all comes down to comparison of input picture, that is the comparison of the biometric face features with the selected face pictures in the database. Facial recognition is mostly used in systems that are connected with safety and usually in two ways: recognition and verification. When it comes to recognizing the face parameters are compared with other faces in the database. For the verification, the face parameters of the person that is using another way of verification in the given moment, are compared with the information of that person in the database. This is done for the sake of making sure that the person who is requesting access is actually a person with allowed access. Even though facial recognition is less precise compared to fingerprint scanning or iris scanning, it is very well accepted because of its non-physical and non-invasive way of use.
