Circle Fitting Library

I'm working on an application that finds a circle in an image. I'm able to detect the edge of the circle along several lines (from the eight compass directions). Given these eight points I now need to determine the circle's center and its radius.

Is there an open source geometry library that provides this function?

Does anyone have code to do this?

Thanks,
Tim
