title: How to ocr low resolution image
body: <p>I have to extract the text from a video which has latitude-longitude data that looks like the following image:</p>
  
  <p><a href="https://i.stack.imgur.com/0L2mr.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0L2mr.jpg" alt="this"></a></p>
  
  <p>The image is very low resolution and tesseract and online OCR failed to extract the text without any processing. I tried to remove grey background using <a href="http://docs.opencv.org/master/db/d5c/tutorial_py_bg_subtraction.html#gsc.tab=0" rel="nofollow noreferrer">this</a>, and subtracting grey colour matrix, but it did not produce meaningful output. I converted to HSV to extract the yellow text but again, got no meaningful results.</p>
  
  <p>I was wondering if there is any way I can extract the text. The most promising lead seems to be that the background is greyscale and the text is translucent yellow.</p>
