How is this related to image processing?

Hi,
I need to identify or find if a particular pattern( Actually it is
hyperbola pattern) is present in an image. Infact, the shape of the
hyperbola can again vary as different shapes and sizes. What part of
image processing is this related. Can anybody point me to certain
topics and resources which will help me do this?
Bye

You could try :

 Ahn, S.J., Rauh, W., Cho, H.S., Warnecke, H.-J., 2002. Orthogonal
distance fitting of implicit curves and surfaces, IEEE Transactions on
Pattern Analysis and Machine Intelligence 24(5), 620-638.

 Ahn, S.J., Rauh, W., Warnecke, H.-J., 2001. Least-squares
orthogonal distances fitting of circle, sphere, ellipse, hyperbola,
and parabola, Pattern Recognition 34(12), 2283- 2303.

I've not read either of these but they should at least have some good 
references.

Best of luck - Mike
