title: regarding understanding the clustering result of slic method for a given image
body: <p>After viewing the result of running <code>slic</code> method over an image</p>
  
  <pre><code>segments = slic(img_adapteq, n_segments = 250, sigma = 5,compactness=0.1)
  </code></pre>
  
  <p>I am curious about one segment cluster that the method returns. In the following image, I use an angle to point to the related cluster. It seems to me this cluster consists of two areas which have distinct pixel intensities. But why they are grouped into a single cluster. Thanks.</p>
