See my image segmentation tutorial, "BlobsDemo" http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

If you need any more help, read this http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer and then come back with your image and m-file.

That doesn't look anything like what my demo creates. What is your original image? Is it the ring-shaped curve? The width looks like 1 pixel. If you fill the ring so that it's a solid ellipse, then the width (minor axis length) would be larger of course.
