I'm not sure how this does not solve your problem. Perhaps if you told me what image you started with and what you actually want to measure I could advise you on the proper way. Often/usually edge detection is not the best way to approach image analysis (not sure why 99% of people think it is). Or if you told me what your "further algorithm" does with the perfect circle (x,y) coordinates.

If you want the outer ounding circle instead of a fitted one, see John D'Errico's code http://www.mathworks.com/matlabcentral/fileexchange/34767-a-suite-of-minimal-bounding-objects

Thanks for the reply Image Analyst,but this did not answer my question .
Actually figure 1 is a result image of after using edge detected techniques for some object . Then i want to trim the edges like perfect circle as figure 2 shows. Because some places of my edge detected circle(figure 1) like a saw-tooth it will cause to come wrong results at the end of my further algorithm . i thing my question now clearly understand sorry for the incomplete question. Can you please help me..
