title: minimum image size for tesseract
body: <p>I am trying to use <code>tesseract</code> to recognize characters from an Image. This image is created by grabbing characters from another image and putting them in a row in a new image. The problem is when I supply this image to <code>tesseract</code> it doesn't show anything in the output but when I paste this image in another image with size <code>640 x 480</code> I get correct results. what is the reason for this behavior? how can I fix this? what am I missing here?</p>
  
  <p>Image without output:
