How does OCR API work?

How does OCR API work

An OCR API is a powerful tool that automates data extraction from various documents and images to help businesses digitize and analyze their important data. Let’s examine how this API integrates and the process involved in data capture.

  • You can set up the OCR API in your system by obtaining an API key from the provider and configuring the necessary settings.
  • Send a request to the OCR API along with the document containing the text you want to extract.
  • Carry out the preprocessing of the image or document to improve text recognition by adjusting contrast and brightness.
  • Analyze the document using the API’s OCR capabilities to identify the shapes and patterns corresponding to specific characters and words.
  • Post-process and send the recognized text back to your system in a usable format after spell-checking and formatting.
  • Use the extracted text in different ways per your requirements, such as database storage or application use.

Now, let’s understand the process we follow to list the APIs.
