Smart Face Recognition Attendance System 🚀

Automated real-time classroom attendance using MediaPipe (Detection), Scikit-Learn (Recognition), SQLite (Database)
Built for SRM IST Trichy & similar colleges | 85-95% accuracy | 25-30 FPS

🎯 Problem Solved

Traditional attendance systems suck:

  • Manual roll call: 5-10 mins wasted per class × 50 classes/day = 8+ hours lost weekly
  • Biometric cards: ₹5k-10k/student hardware, proxy marking common
  • Paper registers: Lost data, manual errors, no analytics
  • No real-time monitoring: Can't tell if classes are empty or teacher absent

Our Solution: Single IP camera detects/tracks students, recognizes faces, logs attendance automatically. Faculty see live dashboard with reports.

💡 Why Better Than Traditional

Feature Manual/Card Our System
Time 5-10 min/class <1 sec/student
Cost ₹5k+/student ₹3k camera/room
Accuracy 95% (proxies) 85-95% (ArcFace)
Scalability 1 room max Multi-room dashboard
Analytics None Live counts, reports, alerts
Privacy N/A Embeddings only (no photos)

Smart Face Recognition Attendance System

A lightweight, Flask-based attendance system that uses Computer Vision to mark attendance automatically using facial recognition.

🚀 How It Works (The Actual Flow)

  1. Capture: The system captures video frames using OpenCV.
  2. Detection: MediaPipe (Google's lightweight model) detects faces in real-time.
  3. Recognition: The face data is processed and compared against a trained Scikit-Learn (KNN/SVM) model stored in model.pkl.
  4. Logging: If a match is found, the student is marked "Present" in the SQLite database (attendance.db).
  5. Interface: A Flask web dashboard displays live stats, allows for CSV exports, and manages student registration.

📋 Tech Stack

  • Backend: Python, Flask (Web Framework)
  • Computer Vision: OpenCV (cv2), MediaPipe
  • Machine Learning: Scikit-Learn (sklearn), NumPy, Pandas
  • Database: SQLite (attendance.db)
  • Frontend: HTML5, CSS3, Bootstrap 5, JavaScript
  • Deployment: Can run locally on any CPU-based laptop.
