Easier image to recognize for OCR
<p>I believe the text result of OCR  not only depends on how good the OCR library is but also <strong>depends on the image to scan</strong>.</p>

<p>My question is that, for an image, how could I make it easier to recognize?</p>

<p>Change the original color? (for example, to grey)</p>

<p>Change the scale/size? (for example, bigger)</p>

<p>Change the area to recognize? (for example, set the distance to top/left side)</p>

<p>Any other idea?</p>
