Live Integrated Facial Observation (L.I.F.O.)
A human face is the most influential part of humans that can uniquely identify a person. Using all the facial characteristics as biometric, the LIFO system can be applicable in many different ways. Like in everyday life, the most mandatory task in any organization is attendance marking. Earlier, people used to mark their presence using paperwork but now along with the advancement of technology, this system has also changed and converted into digital form. Talking about this project, face recognition approach has been taken using open CV. In this model, we have integrated a camera that captures an image as an input, an algorithm for detecting a face from an input image, encoding and identifying the face. After that, record will be automatically updated on a CSV file. The system is then trained on the authorized student faces and the dB is created for the trained data. The database for cropped images is then created along with the associated labels. The features are extracted using Harr Cascade classifier. Not only the attendance system but we can also monitor every behavior of students with the help of their face. Like, analyzing the facial expression, the teachers can conclude if the students understanding their lectures or not. This is done with the help of recently evolved technology i.e. Landmark detector, which is trained with large datasets and exhibits excellent robustness against different angles concerning the camera. It is seen that the precision of eye-opening level are evaluated according to the landmarks. The landmark detector algorithm extracts the scaler quantity eyes-aspect-ratio characterizing the opening of eyes in each frame. Finally, the support vector machine detects the blinking of eyes as a pattern of EAR values and displays it on window. After getting this kind of report, teacher can record the behaviors. Emotion analysis is also going to be part of this project which is very helpful for the teachers. The emotions are sorted into six classes namely anger, joy, surprise, disgust, sadness, and fear from face image datasets. To carry out the particular operation, a camera in several areas like college/classroom, offices, movie auditorium, and in front of a car will be equipped that can be able to recognize the emotions of people introducing a potent new form of artificial intelligence into education for monitoring children for classroom compliance. Here in this project, there will be no existing data about the previous behavior of the students and works on real-time expression tracking.
