title: How to improve image quality?
body: <p>I am making an OCR which reads ID cards. After getting region of interest by using YOLO, I am giving that cropped region to Tesseract to read it. As those cropped images are very small and blurry, Tesseract is unable to read them. When it <em>can</em> read them, it gives wrong predictions. I think that by improving image quality of cropped images, these problems can be solved.</p>
  <p>One of the cropped images:<a href="https://i.stack.imgur.com/JgBcx.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/JgBcx.jpg" alt="A blurry cropped ID card image, reading 8798-7195-7831." /></a></p>
  <p>My question is, how would I go about improving such images?</p>
