i got the center and radius using imfindcircles... how to segment the circular regions out of the image with the centers and radii....

[centers, radii] = imfindcircles(rgb,[20 25]);

What does segment out mean to you? You can create a circular mask from code in the FAQ. http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F

Then you can use the mask as an index, or multiply it by the image to produce an image blackened everywhere except in the mask.
