title: How to match texture similarity in images?
body: <p>What are the ways in which to quantify the texture of a portion of an image? I'm trying to detect areas that are similar in texture in an image, sort of a measure of "how closely similar are they?"</p>
  
  <p>So the question is what information about the image (edge, pixel value, gradient etc.) can be taken as containing its texture information.</p>
  
  <p>Please note that this is not based on template matching.</p>
  
  <p><a href="http://en.wikipedia.org/wiki/Visual_descriptors" rel="noreferrer">Wikipedia</a> didn't give much details on actually implementing any of the texture analyses. </p>
