What do you call a curve? A spline? A polynomial equation? What makes the red curve you've drawn any better than anything else?
Wouldn't the best curve be simply all the boundary pixels (which you'd obtain simply with bwboundaries)?

In order to fit a set of points to something, you first need to define what that something. A curve can mean anything. a line, a spline, a quadratic (like in your first example), a half-ellipse (like in your second example), etc. Until you've decided what class of curve you want to fit, you won't be able to do any fitting.

That green line looks like a half ellipse to me.
