title: Calculating extra attrib. in 3D Matlab's regionprops
body: <p>I have used 'regionprops' to identify regions after a volume segmentation. I need to know the pixel values within each region. The result from 'regionprops' include 'PixelList'. For example, the first region's pixel subscripts in my volume are:</p>
  
  <pre><code>regions(1).PixelList:
  
  
     100    27    73
     100    26    74
      99    25    75
  </code></pre>
  
  <p>There are more than 4000 regions. It takes time as well as being inelegant to go through all the regions in a loop. </p>
  
  <p>How can I get the 'PixelList' for all the regions and calculate the Mean, Max, Min, etc. for every region without using a loop.</p>
  
  <p>Thanks.</p>
