title: Detect text in a scanned page
body: <p>I'm trying to detect the text in a scanned page and get the coordinates of it.
  See the attached image for an example of scanned page.</p>
  
  <p>I need the vertical coordinates for spliting page from the useless parts, and then detect the text's coordinates.</p>
  
  <p>What kind of tools could I use to split and detect text's coordinates?</p>
