title: Opencv cvHoughCircles-Parameters doubts
body: <p>I have some doubts about <code>cvHoughCircles</code> parameters. I have an image that has some circles and I want to count them, the count gives me a wrong number of circles.</p>
  
  <p>So I don't know how to choose some function's parameters like: </p>
  
  <pre><code>dp,min_dist,param1,param2,min_radius, max_radius.
  </code></pre>
  
  <p>I don't know what numbers I use in this parameters. How Can I calculate this?</p>
