🖥️ Platform-Specific Configuration

Windows

# Automatic configuration
{
    "workers": 1,           # Single worker
    "max_workers": 20,      # Reduced thread pool
    "loop": None,          # Default event loop
    "http": None,          # Default HTTP parser
}

Linux/macOS

# High-performance configuration
{
    "workers": 4,           # Multiple workers
    "max_workers": 50,      # Full thread pool
    "loop": "uvloop",      # Faster event loop
    "http": "httptools",   # Faster HTTP parser
}

📚 Usage

Python Package

from face_enhancement_service import FaceEnhancerClient, EnhancementConfig

# Initialize client
client = FaceEnhancerClient("http://localhost:8000")

# Configure enhancement
config = EnhancementConfig(
    smoothing=0.8,
    brightness=0.5,
    whiteness=0.3,
    acne_removal=0.7,
    under_eye_brightening=0.6,
    soft_focus=0.4,
    virtual_contouring=0.5,
    color_temperature=0.2
)

# Enhance image
enhanced_image = client.enhance_image("input.jpg", config)

REST API

# Health check
curl http://localhost:8000/health

# Enhance face
curl -X POST "http://localhost:8000/enhance" \
  -H "Content-Type: application/json" \
  -d '{
    "image": "base64_encoded_image",
    "config": {
      "smoothing": 0.6,
      "brightness": 0.3,
      "whiteness": 0.4,
      "acne_removal": 0.7,
      "under_eye_brightening": 0.5,
      "soft_focus": 0.3,
      "virtual_contouring": 0.4,
