Face Recognition System using OpenCV for Secure Authentication

Abstract

Face recognition system using python leverages the OpenCV library integrated with streamlit for building an interactive, user-friendly face recognition platform.

  • Face recognition is a rapidly evolving and crucial challenge in computer vision, with broad applications in security, education, and healthcare sectors.
  • OpenCV is a versatile and advanced library for image processing, compatible with Python, C++, Java, and other languages.
  • Streamlit enables fast prototyping and deployment of data-driven web interfaces in Python, ideal for AI application demos.
  • In this project, the following key methodologies are implemented:
    • Face Data Collection from Webcam using OpenCV
    • Real-Time Face Detection using Haar Cascade classifier
    • Storing facial images and user metadata for training dataset management
    • Face Recognition using LBPH (Local Binary Patterns Histograms) algorithm
    • Model Training, Prediction, and Confidence Threshold Handling
    • User Database Management for adding/deleting identities via Admin Panel
    • Streamlit-powered interface for seamless data collection, recognition, and administration
  • The system workflow includes:
    • Real-time face detection, capturing and saving grayscale facial images per user
    • Training the LBPH model and persisting it to disk for future recognition
    • Live recognition from webcam feed, labeling known faces based on trained model
    • Allowing administrators to manage the user database and retrain as necessary
  • The combination of OpenCV’s reliable feature extraction and streamlit’s rapid UI deployment creates a robust platform for practical face recognition tasks in academic and industrial settings.

Existing System

  • Existing face recognition systems primarily focus on basic face detection and static recognition without flexible user interaction or dataset management.
  • They often lack features for efficient, user-driven face data collection and dynamic model updating.
  • Current implementations generally do not provide comprehensive options for managing the number of face samples per user or controlling the quality of images collected.
  • Most systems do not include administrative tools for user database management, such as adding or deleting identities through a graphical interface.
  • Real-time display of recognition results is common, but few systems allow live visualization of collected faces or confidence scores in an interactive manner.
  • There is limited customization available for recognition thresholds or labelling accuracy control by end-users.
  • Existing systems rarely output detailed arrays of face data points or recognition metadata for further analysis or user inspection.

Proposed System

  • The proposed face recognition system provides a comprehensive, optimized pipeline for real-time face detection, dynamic dataset management, and live recognition with Streamlit’s interactive interface.
  • Complete customization is available, including:
    • User-controlled number of face images collected per individual.
    • Live monitoring of face sample quality with automatic rejection of poor detections.
    • Adjustable confidence thresholds for recognition labelling, improving reliability.
  • The system enables live display of captured face images and recognition results with clear labelling and feedback.
  • It consolidates face images and recognition metadata as accessible data arrays for easy management and potential further processing.
  • Administrative capabilities allow managing the user database securely with password protection, including adding new users, deleting existing ones, and retraining the model seamlessly.
  • Recognition outputs can be customized with user-preferred visual markers (e.g., bounding box colors and label formats) for better clarity during live recognition sessions.
  • Overall, the system integrates real-time interactivity, customizable parameters, and robust user management unavailable in most existing implementations.
