Applying SOLID with OCR project

In this project, we apply SOLID to build a REST API to receive an Image and return the text from this image.

This project has three big goals:

• Use SOLID and Clean code to create an excellent solution to our problem.
• Use GCP(Google Cloud Platform) with Spring Boot to create services with Machine Learning.
• Use Cloudinary service to help with text extraction.

How to run it

• Install Java 11
• Install Maven
• Include two properties in the application.properties:
  • cloudinary.api-key=$YOUR_API_KEY
  • cloudinary.api-secret=$YOUR_API_SECRET
• Log-in Google Console API, and enable Google Vision API
• Execute: mvn spring-boot:run

Tasks:

• Create an endpoint that receives an image and extracts the text.
• Include the Google OCR and execute it if the Cloudinary service is offline.
• Include the Cotes Storage to prevent charge :)
• Include Text in Storage to be quickly searched
• Include another OCR service
