title: Detecting overlapped elliptical regions in image (MATLAB)
body: <p>I have a multiple plants in a single binary image. How would I identify each leaf in the image assuming that each leaf is approximately elliptical?

  <p>I was thinking a good place to start would be finding the tip of each leaf and then getting the center of each plant. Then I could fit the curves starting from the tip and then going to the center. I've been looking online and saw something involving a watershed method, but I do not know where to begin with that idea. </p>
