Face Recognition Attendance System

This project is a face recognition-based attendance system that uses OpenCV, face_recognition, and Google Sheets for recording attendance. The system captures video from the webcam, recognizes faces, and marks attendance to a Google Sheet. In the absence of an internet connection, it print a message indicating the lack of connectivity.

Features

• Real-Time Face Recognition : Captures video from the webcam and performs face recognition in real-time.
• Face Encoding : Encodes known faces from a specified directory.
• Marks Attendance Automatically : Logs the name and timestamp of recognized faces to a Google Sheet automatically.
• Access Attendance Sheet on Desktop and Smartphone : You can track real-time attendance in Google Sheet on Desktop as well as on your Smartphone.
• Offline Handling : Detects if there is no internet connection and prints a message "No internet connection." and stop the program.
• Daily Logs : Creates a new sheet in the Google Sheets document for each day, organizing attendance records by date.

Installation

1. Clone the Repository :

https://github.com/Param-Sahu/Face_Recognition_Based_Attendance_System.git   

2. Install Dependencies :

• OpenCV and Face_Recognition :

pip install opencv-python face-recognition 

• Install Google Sheet API in Python
  • For Windows

  pip install google-api-python-client google-auth-httplib2 google-auth-oauthlib gspread

  • For Mac

  pip3 install google-api-python-client google-auth-httplib2 google-auth-oauthlib gspread

3. Set Up Google Sheets API : Save the credentials.json file in the project directory (i.e. In the same folder where main.py is saved).
4. Prepare Images : Make sure images of known individuals should be in the attendance_project/images directory.
5. Internet Connection : Make sure you are connected to internet to run this program smoothly.

Functionality

• The script will open the webcam and start capturing frames.
• It will attempt to recognize faces from the frames.
• If a face is recognized and attendance for the day is not already marked, it will log the name and timestamp in the Google Sheets document.
• If there is no internet connection, it will print "No internet connection." and stop the program.

How It Works

Loading and Encoding Faces :

• The load_images_and_encode_faces function loads face images from the specified directory and encodes them using the face_recognition library.

Google Sheets Setup :

• The script uses the gspread library to connect to Google Sheets using the provided service account credentials.
• It creates a new sheet for the current date if it doesn't already exist.

Face Recognition and Attendance Logging :

• The webcam captures frames which are processed to detect and recognize faces.
• Recognized faces are checked against the attendance log for the day.
• If a face is recognized and attendance is not already marked, the name and timestamp are logged in the Google Sheets document.

Notes

• Ensure the Google Sheets API is enabled for your Google Cloud project and the service account has edit access to the Google Sheets document.
• You can configure the script to run for a different duration or adjust other parameters as needed.
