## 🚀 Quick Start

### Installation

```bash
# Basic installation
pip install myfacedetect

# With advanced features (recommended)
pip install myfacedetect[advanced]

# Development installation
git clone https://github.com/yourusername/myfacedetect.git
cd myfacedetect
pip install -e .
```

### CPU-only Quick Start

If you are on a CPU-only system (no GPU), a lightweight setup and scripts are provided in `docs/CPU_SETUP.md` and `examples/`.

PowerShell quick commands:

```powershell
python -m venv facedetect_env
facedetect_env\Scripts\activate
pip install --upgrade pip
pip install -r requirements.txt
python scripts/test_setup.py
python examples/detect_faces_live.py
```

This will run the provided CPU-friendly live detection and example utilities.


### Basic Usage (Backward Compatible)

```python
from myfacedetect import detect_faces, detect_faces_realtime

# Detect faces in image
faces = detect_faces("image.jpg", method="mediapipe")
print(f"Found {len(faces)} faces")

# Real-time detection
detect_faces_realtime(method="both")
```

### Modern Modular API

```python
from myfacedetect import DetectorFactory, ConfigManager

# Load configuration
config = ConfigManager()

# Create high-accuracy detector
detector = DetectorFactory.create_detector(
    'ensemble', 
    config.get_pipeline_config('high_accuracy')
)

# Detect faces
import cv2
image = cv2.imread("image.jpg")
results = detector.detect_faces(image)

for face in results:
    print(f"Face: {face.x}, {face.y}, {face.width}x{face.height}, confidence: {face.confidence}")
```

## 🎯 Pipeline Configurations

Choose from predefined pipelines optimized for different scenarios:

```python
from myfacedetect import ConfigManager

config = ConfigManager()

# Available pipelines
pipelines = [
    'default',      # Balanced speed and accuracy
    'high_accuracy', # Maximum accuracy for critical applications  
    'realtime',     # Optimized for real-time processing
    'security',     # Enhanced security with liveness detection
    'privacy',      # Privacy-preserving processing
    'mobile'        # Lightweight for mobile/edge devices
]

# Use specific pipeline
detector_config = config.get_pipeline_config('high_accuracy')
detector = DetectorFactory.create_detector('ensemble', detector_config)
```

## 🔍 Detection Methods Comparison

| Method | Speed | Accuracy | Resource Usage | Best For |
|--------|-------|----------|----------------|----------|
| **Haar** | ⚡⚡⚡ | ⭐⭐ | 💾 Low | Legacy systems, embedded |
| **MediaPipe** | ⚡⚡ | ⭐⭐⭐ | 💾💾 Medium | General purpose, mobile |
| **RetinaFace** | ⚡ | ⭐⭐⭐⭐⭐ | 💾💾💾 High | Critical accuracy needs |
| **YOLOv8** | ⚡⚡⚡ | ⭐⭐⭐⭐ | 💾💾 Medium | Real-time applications |
| **Ensemble** | ⚡ | ⭐⭐⭐⭐⭐ | 💾💾💾💾 Very High | Maximum reliability |

## 🧠 Face Recognition

```python
from myfacedetect import create_face_recognizer, create_face_database

# Create recognition system
recognizer = create_face_recognizer('arcface')  # or 'facenet', 'opencv'
database = create_face_database("face_db")

# Add person to database
success = recognizer.add_face(face_image, "John Doe", {"department": "Engineering"})

# Recognize face
name, confidence = recognizer.recognize_face(unknown_face)
if confidence > 0.8:
    print(f"Recognized: {name} (confidence: {confidence:.2f})")
else:
    print("Unknown person")

# Database statistics
stats = recognizer.get_statistics()
print(f"Database: {stats['total_people']} people, {stats['total_faces']} faces")
```

## 🔒 Security Features

### Liveness Detection

```python
from myfacedetect import create_liveness_detector

detector = create_liveness_detector()

# Start liveness challenge
challenge = detector.start_liveness_check('blink')  # or 'smile', 'turn_head'

# Process video frames
while True:
    result = detector.process_frame(frame, face_bbox)
    
    if result['status'] == 'success':
        print("✅ Liveness verified!")
        break
    elif result['status'] == 'in_progress':
        print(f"👁️ {result.get('instruction', 'Continue...')}")
```

### Privacy Protection

```python
from myfacedetect import create_privacy_protector

protector = create_privacy_protector()

# Anonymize faces in image
anonymized = protector.anonymize_faces(image, faces, method='blur')

# Privacy-preserving embeddings
private_embedding = protector.differential_privacy_embedding(embedding, epsilon=1.0)

# Secure face hashing
face_hash = protector.create_face_hash(embedding, salt="secret_salt")
```

## ⚡ Performance Optimization

### GPU Acceleration

```python
from myfacedetect import create_gpu_accelerator

gpu = create_gpu_accelerator()

# Check GPU support
if gpu.cuda_available:
    print("🚀 CUDA acceleration available")
    
# Benchmark performance
results = gpu.benchmark_gpu_performance(test_image)
print(f"GPU speedup: {results.get('speedup', 1.0):.1f}x")
```

### Intelligent Caching

```python
from myfacedetect import create_intelligent_cache

cache = create_intelligent_cache(
    max_memory_items=1000,
    max_disk_size_mb=100
)

# Cache automatically used by detectors
# Or use manually:
cache_key = cache.get_detection_cache_key(image, detector_name, config)
result = cache.get(cache_key)
if result is None:
    result = detector.detect_faces(image)
    cache.set(cache_key, result)
```

## 🎨 Advanced Preprocessing

```python
from myfacedetect import FaceAligner, ImageEnhancer

# Enhance image quality
enhancer = ImageEnhancer()
enhanced = enhancer.enhance_lighting(image, method='adaptive')
denoised = enhancer.denoise_image(enhanced, method='bilateral')

# Align faces
aligner = FaceAligner(desired_face_width=224, desired_face_height=224)
aligned_face = aligner.align_face(image, face_bbox)

# Complete preprocessing pipeline
config = {
    'enhance_lighting': True,
    'lighting_method': 'clahe',
    'denoise': True,
    'denoise_method': 'bilateral',
    'normalize': True,
    'super_resolution': False
}
processed = enhancer.preprocess_pipeline(image, config)
```

## 🛠️ Advanced Configuration

Create custom configurations in YAML:

```yaml
# custom_config.yaml
device: 'cuda'  # or 'cpu', 'auto'
detection:
  confidence_threshold: 0.7
  nms_threshold: 0.4
  max_faces: 10
preprocessing:
  enhance_lighting: true
  lighting_method: 'adaptive'
  denoise: true
  face_alignment: true
postprocessing:
  apply_nms: true
  filter_small_faces: true
  min_face_size: 30
```

```python
config = ConfigManager()
config.load_config('custom_config.yaml')
detector = DetectorFactory.create_detector('ensemble', config.get_config())
```
