title: Is there any way to improve tesseract OCR with small fonts?
body: <p>I'm trying to use tesseract-OCR via python-tesseract to read a low resolution font that looks like this:
  <br><br></p>
  
  <p><img src="https://i.stack.imgur.com/76K3V.gif" alt="enter image description here"></p>
  
  <p>Unfortunately that image returns </p>
  
  <pre><code>ZIJZHZI
  </code></pre>
  
  <p>I think the resolution is too low and that is causing problems. I've tried magnifying the image, and cropping it down to individual characters, but neither of these provide much improvement. Is there anything else I should consider doing, preferably something that could be done using the Python Imaging Library? Or should I just give up/train tesseract.</p>
  
  <p>For what it's worth, the PIL has the following built in filters:</p>
  
  <blockquote>
    <p>BLUR, CONTOUR, DETAIL, EDGE_ENHANCE,<br>
    EDGE_ENHANCE_MORE, EMBOSS, FIND_EDGES,<br>
    SMOOTH, SMOOTH_MORE, and SHARPEN</p>
