Evaluating/Fitting an ellipse from scattered points

Question

Here is the deal. I have multiple points (X,Y) that form an \'ellipse like\' shape.

I would like to evaluate/fit the \'best\' ellipse possible and get its properties

Answer 1

There's a Matlab function fit_ellipse that can do the job. There's also this paper on methods for orthogonal distance fitting of ellipses. A web search for orthogonal ellipse fit will probably turn up a lot of other resources as well.
