Hi. I need to automatically find six ellipses in an image like this:
I tried using imfindcircles, but it did not work, because the figures are not circles. Any hint?
Thanks in advance.

If you just need the centers of the six ellipses, just increase the sensitivity of imfindcircles. It will tolerate rather non-circular features. You can use a tight radius cutoff to reduce any background.
