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 generate wrong results at the end of my further algorithm . i thing my question now clearly understand sorry for the incomplete question. Anyone know the solution for this...
Thank you Best regard!

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
