# Real-World Case Study: E-commerce Product Pipeline
import boto3
from PIL import Image
import io
def process_product_image(s3_bucket, s3_key):
# 1. Download from S3
s3 = boto3.client('s3')
response = s3.get_object(Bucket=s3_bucket, Key=s3_key)
img = Image.open(io.BytesIO(response['Body'].read()))
# 2. Standardize dimensions
img = img.convert("RGB")

# 3. Remove background (simplified)
# In practice: use rembg or AWS Rekognition

# 4. Generate variants
