title: OpenCV + Tesseract for text recognition on video frames in realtime
body: <p>I am trying to use tesseract for frames captured by opencv from windows screen. I am not using a camera feed here instead I am trying to capture certain message that appears in a message box of a certain color. I am able to crop out the part of the screen that shows the message box and I want to use tesseract for reading the message. I am able to read the message using tesseract from the screenshot of the same message box cropped image but when I try to do the same in real time screen capture it is giving really bad output.</p>
  
  <p>The screenshot is saved using imwrite() of opencv on the same Mat image which is passed to tesseract.</p>
  
  <p>Can anyone explain why is this happening?</p>
  
  <p>How can I make it work?</p>
  
  <p>Regards</p>
