Algorithms: Ellipse matching

Viewed 1873

I have many images like the following (only white and black):

My final problem is to find well matching ellipses. Unfortunately the real used images are not always that nice like this. They could be deformed a bit, which makes ellipse matching probably harder.

My idea is to find "break points". I markes them in the following picture:

Maybe these points could help to make a matching for the ellipses. The end result should be something like this:

Has someone an idea what algorithm may be used to find these break points? Or even better to make good ellipse matching?

Thank you very much
