The working principle of the IoT-Based Face Recognition Attendance Management System using Raspberry Pi shown in Fig.2 involves the following steps:
1. Initialization:
o The Raspberry Pi powers up and initializes the camera module and the face recognition software.
2. Image Capture:
o As individuals approach the attendance point, the camera module continuously captures their images.
o The system may use motion detection to trigger image capture, ensuring it only processes relevant frames.
3. Face Detection and Preprocessing:
o The captured images are processed to detect faces. This involves identifying the region of interest (ROI) that contains the face.
o The detected face is then pre-processed (e.g., resized, normalized) to enhance recognition accuracy.
4. Facial Recognition:
o The pre-processed face image is fed into the facial recognition algorithm, which compares it against a database of registered faces.
o The algorithm uses feature extraction and matching techniques to identify the individual.
5. Attendance Logging:
o Upon successful identification, the system logs the attendance data, including the individual's identity and timestamp.
o The attendance record is stored locally on the Raspberry Pi and/or uploaded to the cloud for remote access.
6. Real-time Alerts and Notifications:
o The system can generate real-time alerts or notifications (e.g., confirmation of attendance) to the individual and administrators.
7. Remote Access and Management:
o Authorized personnel can access the attendance records remotely via a web interface or mobile app.
o The system provides various management functions, including adding/removing users, generating attendance reports, and configuring system settings.
