🧠 Model Architecture

Face Detection

• MTCNN: Multi-task CNN for robust face detection
• Confidence Threshold: 90% minimum confidence for face detection
• Multi-scale Detection: Handles various face sizes

Face Recognition

• FaceNet: InceptionResNetV1 pre-trained on VGGFace2
• Embedding Size: 512-dimensional face embeddings
• SVM Classifier: Support Vector Machine for identity classification
• Cosine Similarity: For duplicate detection and clustering

Training Pipeline

1. Face detection using MTCNN
2. Face alignment and normalization
3. Feature extraction with FaceNet
4. L2 normalization of embeddings
5. SVM training with cross-validation
6. Model serialization with joblib

🚀 Deployment

Streamlit Cloud (Recommended)

1. Push code to GitHub
2. Visit share.streamlit.io
3. Connect your repository
4. Deploy with one click!

Local Development

# Install dependencies
pip install -r requirements.txt

# Run desktop app
python final9.py

# Run web app
streamlit run streamlit_app.py

Docker Deployment

# Build Docker image
docker build -t face-recognition .

# Run container
docker run -p 8501:8501 face-recognition

🔧 Configuration

Model Parameters

• Image Size: 160x160 pixels for face extraction
• Margin: 20 pixels around detected faces
• Confidence Threshold: 40% for identity classification
• Duplicate Threshold: 75% cosine similarity

Performance Optimization

• Frame Skipping: Process every 3rd frame for real-time performance
• Model Caching: Streamlit caching for faster load times
• GPU Acceleration: Automatic CUDA detection and usage
• Memory Management: Efficient queue handling for camera processing

🛡️ Security & Privacy

• Local Processing: All face recognition happens locally
• No Data Collection: No personal data is stored or transmitted
• Secure Models: Encrypted model files (optional)
• Privacy First: Camera access only when explicitly granted

🔍 Troubleshooting

Common Issues

Camera Not Working

• Desktop: Check camera permissions and drivers
• Web: Ensure HTTPS connection for camera access
• Alternative: Use file upload instead of camera

Model Loading Errors

• Ensure all model files are present in the project directory
• Check file permissions and paths
• Verify model file integrity

Performance Issues

• GPU: Install CUDA for better performance
• Memory: Reduce image resolution for large batches
• CPU: Use frame skipping for real-time processing

Dependencies

# Update dependencies
pip install --upgrade -r requirements.txt

# Clear cache (Streamlit)
streamlit cache clear
