Post the image to the web somewhere (e.g. tinypic.com), and post the link to it here. That will help us give you specific information.

See my Image Segmentation Tutorial: BlobsDemo - it does that using the standard coins demo. There is also a Mathworks demo on Steve's blog using imfindcircle: http://blogs.mathworks.com/steve/2012/09/04/detecting-circular-objects-in-images/
