SupVision-Venom 🎓

A comprehensive AI-powered attendance management system that uses facial recognition technology to automatically track student attendance in educational institutions.

🚀 Project Overview

SupVision-Venom is a dual-service architecture consisting of:

1. Main Application (supvision/) - Flask-based REST API for managing students, schedules, attendance, and user authentication
2. Model Server (model_server/) - Dedicated service for face recognition processing using advanced AI models

Key Features

• 🎯 Automated Face Recognition - Uses InsightFace and FAISS for high-accuracy student identification
• 📊 Attendance Management - Track and manage student attendance with detailed records
• 👥 Student Management - Complete CRUD operations for student data
• 📅 Schedule Management - Class scheduling and timetable management
• 🔐 User Authentication - Secure user management with bcrypt encryption
• 📸 Image Processing - Upload and process class photos for attendance
• 🗄️ MongoDB Integration - Scalable data storage with GridFS for image files
• 🐳 Docker Support - Easy deployment with Docker Compose

🚀 Quick Start

Prerequisites

• Docker and Docker Compose
• Python 3.8+ (for local development)
• MongoDB (if running locally)

Using Docker (Recommended)

1. Clone the repository

   git clone <repository-url>
   cd supVision-venom

2. Start all services

   docker-compose up --build

3. Access the services

   • Main API: http://localhost:5000
   • Model Server: http://localhost:8000
   • MongoDB: localhost:27017

Local Development

1. Install dependencies

   # Main application
   cd supvision
   pip install -r requirements.txt
   
   # Model server
   cd ../model_server
   pip install -r requirements.txt

2. Start MongoDB

   # Using Docker
   docker run -d -p 27017:27017 --name mongo mongo:6.0
   
   # Or install MongoDB locally

3. Run the services

   # Terminal 1 - Main application
   cd supvision
   python app.py
   
   # Terminal 2 - Model server
   cd model_server
   python app.py

🔧 Configuration

Environment Variables

# MongoDB
MONGO_URI=mongodb://localhost:27017/venom

# Flask
FLASK_ENV=development
FLASK_APP=app.py
DEBUG=True

Docker Configuration

The docker-compose.yml file configures:

• MongoDB service with persistent volume
• Main application service
• Model server service
• Network connectivity between services

🎯 Usage Workflow

1. Setup Students: Add student records with face embeddings
2. Create Schedule: Define class schedules and subjects
3. Upload Class Photos: Upload images of the class
4. Process Attendance: Use face recognition to identify students
5. View Reports: Access attendance records and analytics

🔍 Face Recognition Process

1. Image Upload: Class photos are uploaded to the system
2. Face Detection: InsightFace detects faces in the images
3. Feature Extraction: Face embeddings are extracted and normalized
4. Matching: FAISS performs similarity search against student database
5. Attendance Marking: Students are identified and marked present/absent

🛡️ Security Features

• Password hashing with bcrypt
• Secure file upload validation
• CORS configuration for cross-origin requests
• Input validation and sanitization

📝 Development Notes

• The system uses FAISS for efficient vector similarity search
• Face embeddings are stored as binary data in MongoDB
• Images are stored using GridFS for scalability
• The model server can be scaled independently
