title: How to use Opencv for Document Recognition with OCR?
body: <p>I´m a beginner on computer vision, but I know how to use some functions on opencv. I´m tryng to use Opencv for Document Recognition, I want a help to find the steps for it. </p>
  
  <p>I´m thinking to use opencv example find_obj.cpp , but the documents, for example passport, has some variables, name, birthdate, pictures. So, I need a help to define the steps for it, and if is possible how function I have to use on the steps. </p>
  
  <p>I'm not asking a whole code, but if anyone has any example link or you can just type a walkthrough, it is of great help.</p>
