WebOnces you have parametric equation that describes the shape you can build parameter space and detect that shape. For the circle. r2 = (x−x0)2 +(y−y0)2. Circle parameters are center (x0,y0) and radius r. Your parameter space now is 3D parameter space. Think how to extend the basic Hough line transform to detect circles.
