Fitting my own curve for a set of data

Hi,
I am doing some research on curve fitting, but with a slightly
different kind of problem. I have started reading about curve fitting
using different methods but my problem statement is as follows:
I have a reference template curve of a particular kind. It
is a closed curve of a particular shape. I dont know any mathematical
equation describing that curve. I mean to say that it has not been
expressed in the form of any equation like a circle or any ellipse can
be expressed. It has actually been got by doing edge detection over a
boundary of a perfect shape in an image.
Now I use this shape as a reference curve.
I then have another set of data points got by doing edge detection over
another image having this shape but with little bit of noise. This
results in a set of data points over which I have to fit the reference
curve.
Can you give me few pointers on this topic? Is it possible to fit the
reference curve over the data points when I don't have any equation
representing the original curve.
What are the books/links/reference links which provide me good
information on this topic?
Please don't give me the final solution as I want to do my own homework
on this. just few ideas and pointers would help a lot.
With Regards,
Abhishek S
