Description

Amazon Rekognition allows you to detect objects and scene details from images. It provides a stateless and secure API that simply returns a list of related labels, with a certain confidence level.

In this hands-on lab, you will build a serverless system that runs object detection when images are uploaded to an Amazon S3 bucket. You will use AWS Lambda for the processing logic and you will use Amazon DynamoDB to store the results of the label detection.

Learning Objectives

Upon completion of this beginner-level lab, you will be able to:

  • Create an Amazon S3 bucket
  • Create an AWS Lambda function
  • Configure an AWS Lambda function to trigger on an upload to Amazon S3
  • Implement image label detection using Amazon Rekognition and Python

Intended Audience

  • Cloud Engineers
  • Data Engineers
