Detecting Text in an Image Using Amazon Rekognition

In this Cloud Lab, you’ll learn to extract text from an image using the AWS image recognition service—Rekognition. You’ll deploy a Lambda function that triggers by uploading an image to the S3 bucket and stores the results retrieved from Rekognition in the S3 bucket.

Cloud Lab Overview

AWS Image Rekognition is an advanced image analysis service that uses machine learning to identify faces, scenes, and objects in images and videos. In this Cloud Lab, you’ll learn to use AWS S3 bucket, Lambda function, Lambda function trigger, and Rekognition to automate image analysis tasks. Understanding this technology is essential for any developer who wants to automate image analysis tasks and increase the efficiency of their work.

This Cloud Lab will cover the following tasks in sequential order—you’ll learn to create an S3 bucket, configure a Lambda function, set up a Lambda function trigger, and integrate Rekognition to analyze images. You’ll also learn to implement the analysis of images and recognize text. After this, you’ll learn to perform an action based on the analysis, such as sending an alert or storing the results in a database.

After completing this Cloud Lab, you’ll be able to automate tasks, such as monitoring security cameras, analyzing product images for e-commerce, or detecting inappropriate content in user-generated images. This knowledge of cloud services and automation will advance your career as a developer and help in the efficiency and productivity of your work.

I prefer Educative courses because they have a nice mix of text & images. I find that with full video courses, it can often be too easy to go into passive learning mode.
