title: Find the center coordinate of a circle from a list of pixel coordinates C#
body: <p>I have a BitMap image where the image contains a black circle. I have found all the pixels from the image that are black which represent the circle and have saved the points into a List.</p>
  
  <p>Where I am lost is finding the center of the circle from coordinates saved in the list. I am thinking that I need to find the diameter of the circle somehow but how do I loop though the pixels to do that to determine that?</p>
