Dear everybody,

I am new to ImageJ and I am trying to automate the task of manually selecting a circular ROI.

I have this kind of images and I want everytime ImageJ to automatically detect the inside membrane, which is not exactly in the same position in every image. Then I want to Clear the Outside, so I can work on the region I am interested in. I tried with the plugin Hough Circles, but it doesn't really work; when I try to use it ImageJ crashes and I am not sure if it could give me the result I want, since I cannot use it.

It would be really helpful if somebody could give me some advice. Is there an available plugin which could perform this task?

Thank you in advance.
Maria
