Are the (x,y) co-ordinates of detected circles stored? If so, how can i access them?

Hello, I want to know if there's a similar algorithm to detect ellipse in an image.
I want to detect the edge of a vehicle wheel's rim when it has been rotated on all the three axes (in 3D). This algorithm by Mr. Tao Peng (CircularHough_Grd) works very well when the rim looks like a circle. But when it resembles an ellipse, due to rotation about all the three axes, it fails to detect the rim.
Kindly help.
