US Visa OCR

 

This article walks you through the building process of an OCR API that extracts data from US Visas using our deep learning engine. It will work for any visa issued by the United States of America.  

 

 

Prerequisites

  1. You’ll need a free beta account. Sign up and confirm your email to login.
  2. You’ll need at least 20 US Visa images or pdfs to train your OCR.

 

 

Define your US Visa use case

 

First, we’re going to define what fields we want to extract from your US Visa. 

 

 

US Visa OCR API

 

 

  • First name: The first name of the visa holder (Happyperson)

 

  • Last name: The last name of the visa holder (Traveler)

 

  • Passport number: The passport number of the visa holder (AB1234567)

 

  • Control Number:  The visa control number (20191234567890)

 

  • Visa type: The visa type appearing on the US Visa (B1/B2)

 

 

That’s it for our use case. Feel free to add any other relevant data to fit your requirements.

 

 

Deploy your API

 

Once you have defined the list of fields you want to extract, head over to the platform and press the ‘build a new endpoint’ button.

 

You land now on the setup page. Here is the image you can use for setting up the API, and my setup looks like this:

 

 

Set up your US Visa OCR API

 

Once you’re ready, click on the “next step” button. We are going to specify the data types for each of the fields we want our API to extract.


 

To go further, you can download this json config to set up your data model or do it manually.


 

First name: type String that never contains numeric characters.

Once you’re done setting up your data model, press the Data model ready? start training button at the top of the screen.

 

 

Train your US Visa OCR

 

 

Deep learning US Visa OCR training

 

 

You’re all set! 

 

Now is the time to train your US Visa deep learning model in the Training section of our API. 

 

 

In a few hours (minutes if you're fast), you’ll get your first model trained and will be able to use your custom OCR API for parsing US Visa in your application.
