title: What do the parameters in Hough Circle signify and how to know what values to use?
body: <p>While using hough circle, I didn't quite understand how to define the parameters for hough circles? I also don't even know what the parameters they signify. As far as I know</p>
  
  <ul>
  <li><code>image</code>: It is the source image </li>
  <li><code>method</code>: It is the process it uses to detect the circles,(are there any other than hough gradient)</li>
  <li><code>minDist</code>: is the min. distance between two centres of a circle</li>
  <li><code>minRadius</code>: It the min radius of the circles</li>
  <li><code>maxRadius</code>: It is the max radius </li>
  </ul>
  
  <p>The rest of the parameters I don't even understand. Can someone help to explain this to me.</p>
