How to automate object detection with Amazon Rekognition

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 order to automate the labels extraction process, we will build a serverless system that runs object detection on every image uploaded to S3. We will use AWS Lambda for the processing logic and save the results on a DynamoDB table.

We will see how to setup S3, DynamoDB, and AWS Lambda to automate the whole process. During this Laboratory, we will also discuss its API details, optional parameters, best practices, etc.
