title: can anyone please elaborate on cvWatershed() function
body: <p>cvWatershed() takes two arguments Iplimage *src_image and CvArr* markers.</p>
  
  <p>Could anyone elaborate on the markers argument since I need to segment my image on the basis of my touch, so could the marker array be formed in realtime on the basis of my touch and then cvWatershed be called..?</p>
