Using Facial Recognition for a Robust, Real-time Attendance System
There is a growing need to use technology to mark the attendance of students in the classroom – a process that is both automatic as well as efficient. In recent years, the problem of attendance management has been addressed through the use of standard biometrics like fingerprint or iris scanners. However, most proposed technologies are not too reliable. One solution is the intelligent application of facial recognition techniques iteratively. This article discusses an automated attendance management system that uses facial recognition.

In this month’s column, we continue our discussion on the testing of machine learning applications, focusing our discussion on NLP.
