## Quality Tips

### Best Results When:
- Subject is clearly defined
- Good contrast with background
- Adequate lighting
- High resolution input

### Challenging Cases:
- Wispy hair
- Transparent objects
- Similar colors to background
- Motion blur

### Post-Processing
```python
from PIL import Image

# Load result with transparency
img = Image.open('result.png')

# Add solid color background
background = Image.new('RGBA', img.size, (255, 255, 255, 255))
background.paste(img, mask=img.split()[3])
background.save('white_bg.png')

# Add gradient background
# ... gradient generation code
```

## Batch Processing

### Remove.bg Batch
```python
import os
import requests

images = ['photo1.jpg', 'photo2.jpg', 'photo3.jpg']

for img_path in images:
    response = requests.post(
        'https://api.remove.bg/v1.0/removebg',
        files={'image_file': open(img_path, 'rb')},
        headers={'X-Api-Key': API_KEY}
    )
    output_path = img_path.replace('.jpg', '_nobg.png')
    with open(output_path, 'wb') as f:
        f.write(response.content)
```

## iOS Integration

```swift
import UIKit

func removeBackground(image: UIImage) async throws -> UIImage {
    guard let imageData = image.jpegData(compressionQuality: 0.9) else {
        throw ImageError.invalidImage
    }

    var request = URLRequest(url: URL(string: "https://api.remove.bg/v1.0/removebg")!)
    request.httpMethod = "POST"
    request.setValue(apiKey, forHTTPHeaderField: "X-Api-Key")

    // ... multipart form data setup
