📖 **For complete documentation, see [COMPLETE_GUIDE.md](COMPLETE_GUIDE.md)**

## 🚀 Quick Start (Copy & Paste This!)

```bash
cd /path/to/your/facerecognition
source venv/bin/activate
python demo.py

Choose Option 4 for fastest recognition or Option 1 for basic detection!

⚡ NEW: Performance Optimized Options

• Option 4: ⚡ Fast Recognition (5x faster, real-time)
• Option 3: 👤 Regular Recognition (2x faster, balanced)

🎮 Camera Controls

• Q - Quit | S - Screenshot | F - Save faces | H - Help

🚨 Fix "No module named 'cv2'" Error

# Always activate the virtual environment first!
source venv/bin/activate

✅ CONFIRMED WORKING FEATURES

• 🎥 Real-time face detection (OpenCV)
• 🧠 Advanced face recognition (Deep Learning)
• 💾 Screenshot & face saving
• 👤 Face database management
• 🎮 Interactive controls

Features

Simple Face Detection (OpenCV)

• Real-time face detection using Haar Cascades
• Works out of the box with minimal setup
• Save detected faces and screenshots
• Basic face counting

Advanced Face Recognition (face_recognition library)

• High-accuracy face recognition using deep learning
• Add and recognize known faces
• Confidence scoring
• Face database management

Installation

Quick Setup

# Make setup script executable and run it
chmod +x setup.sh
./setup.sh

Manual Installation

# Create virtual environment
python3 -m venv venv
source venv/bin/activate

# Install system dependencies (macOS)
brew install cmake

# Install Python packages
pip install -r requirements.txt

Usage

Quick Start

# STEP 1: Navigate to the project directory
cd /path/to/your/facerecognition

# STEP 2: Activate virtual environment (REQUIRED!)
source venv/bin/activate

# STEP 3: Run the demo application
python demo.py

🚨 CRITICAL: You must activate the virtual environment (source venv/bin/activate) before running any Python commands, or you'll get "No module named 'cv2'" errors!

Individual Applications

Simple Face Detection

Troubleshooting

❌ Error: "No module named 'cv2'"

This is the most common issue!

💡 Solution:

# STEP 1: Navigate to project directory
cd /path/to/your/facerecognition

# STEP 2: Activate virtual environment (REQUIRED!)
source venv/bin/activate

# STEP 3: Verify environment is active (you should see "(venv)" in prompt)
# STEP 4: Run the application
python demo.py

🚀 Quick Fix: Use the launcher script

./start.sh

Other Issues:

• Advanced face recognition not working: Try the simple face detection first (it requires fewer dependencies)
• Camera issues: Make sure cmake is installed: brew install cmake
• Setup problems: Run the setup test: python test_setup.py
• Camera not accessible: Check that your camera is not being used by another application

Requirements

• Python 3.8+
• macOS/Linux (Windows support may require additional setup)
• Webcam or camera device
• For advanced features: cmake and compilation tools
