# Example: Image Recognition Lambda Function
import json
import boto3
import base64
from decimal import Decimal

rekognition = boto3.client('rekognition')
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('ImageMetadata')

def lambda_handler(event, context):
    # Extract image from API Gateway event
    image_data = base64.b64decode(event['body'])
    
    # Analyze image with Rekognition
    response = rekognition.detect_labels(
        Image={'Bytes': image_data},
        MaxLabels=20,
        MinConfidence=70
    )
    
    # Extract detected labels
    labels = []
    for label in response['Labels']:
        labels.append({
            'Name': label['Name'],
            'Confidence': Decimal(str(label['Confidence'])),
            'Categories': label.get('Categories', [])
        })
    
    # Detect text in image
    text_response = rekognition.detect_text(
        Image={'Bytes': image_data}
    )
    
    # Store metadata in DynamoDB
    item = {
        'ImageId': event['requestContext']['requestId'],
        'Timestamp': event['requestContext']['requestTime'],
        'Labels': labels,
        'DetectedText': text_response['TextDetections'],
        'UserId': event['requestContext']['authorizer']['principalId']
    }
    
    table.put_item(Item=item)
    
    return {
        'statusCode': 200,
        'headers': {
            'Access-Control-Allow-Origin': '*',
            'Content-Type': 'application/json'
        },
        'body': json.dumps({
            'imageId': item['ImageId'],
            'labels': labels,
            'textDetected': len(text_response['TextDetections']) > 0
        })
    }
