I have a mask with outlines of ellipses. I am trying to locate their centers. So far I tried using cv2.HoughCircles, but that does not work properly.

I tried scaling the image so that ellipses become more like circles, but that does not work with cv2.HoughCircles either.

Outlines are not continuous so I tried morphological operations, but the gaps are very large and by the time I close gaps on a larger ellipse, the smaller ones are gone.

Any suggestions?

elipses

Thanks.

    Have a look [here](http://stackoverflow.com/a/35651948/5008845). I recommend the methods of Prasad or Libuda for this kind of images – Miki Jan 13 '17 at 01:47
