title: PixelList in regionprops
body: <p>I want to map the output of <code>regionprops</code> to the original image. What does the <code>'PixelList'</code> attribute of the output of <code>regionprops</code> denote?</p>
  
  <p>When I try to access the pixels whose locations are specified by the <code>'PixelList'</code> attribute, they sometimes exceed the dimensions of the original image. Is this the correct interpretation?</p>
