🔧 API Usage Example

from PIL import Image
from rembg import remove, new_session

# Basic usage
input_image = Image.open('input.jpg')
output_image = remove(input_image)
output_image.save('output.png')

# Advanced usage with specific model
session = new_session('u2net_human_seg')
output_image = remove(input_image, session=session)
output_image.save('output.png')

# With alpha matting for better quality
output_image = remove(
    input_image,
    alpha_matting=True,
    alpha_matting_foreground_threshold=270,
    alpha_matting_background_threshold=20,
    alpha_matting_erode_size=11
)
output_image.save('output.png')
