Hi,

What do you mean by rectangle? Is that a feature in the image or an object you've created with something like imrect?
By biggest, do you mean largest area or something else?

You forgot to post your image. So all I can do is to refer you to my Image Segmentation Tutorial in my File Exchange and to the attached demo that takes the largest region(s).

OK, I see it now. My demo code will work. Just modify it slightly to read in your image instead of mine and invert it so that the rectangles are bright and the background black.
