Python
SDK for Python (Boto3)

Shows you how to use the Amazon SDK for Python (Boto3) to create a web application that lets you do the following:

  • Upload photos to an Amazon Simple Storage Service (Amazon S3) bucket.

  • Use Amazon Rekognition to analyze and label the photos.

  • Use Amazon Simple Email Service (Amazon SES) to send email reports of image analysis.

This example contains two main components: a webpage written in JavaScript that is built with React, and a REST service written in Python that is built with Flask-RESTful.

You can use the React webpage to:

  • Display a list of images that are stored in your S3 bucket.

  • Upload images from your computer to your S3 bucket.

  • Display images and labels that identify items that are detected in the image.

  • Get a report of all images in your S3 bucket and send an email of the report.

The webpage calls the REST service. The service sends requests to Amazon to perform the following actions:

  • Get and filter the list of images in your S3 bucket.

  • Upload photos to your S3 bucket.

  • Use Amazon Rekognition to analyze individual photos and get a list of labels that identify items that are detected in the photo.

  • Analyze all photos in your S3 bucket and use Amazon SES to email a report.

For complete source code and instructions on how to set up and run, see the full example on GitHub.
