title: Erosion in MATLAB
body: <p>When I apply <a href="http://en.wikipedia.org/wiki/Erosion_%28morphology%29" rel="nofollow noreferrer">erosion</a> to my image to find a small ball or disk shaped objects, no matter how much I change the size of the structuring element it doesn't seem to work. Instead the entire image appears kind of smudged by the structuring elements. I can still see where the objects are, but it doesn't help me locate them. Is there a way to refine this technique?</p>
