Simple task on image

Dear all,

I've binary image with white border . There is a huge circle with white border and its border touch the border of the image at up & down. There are some white small regions in the circle. I want to remain only white regions in the image. The borders are necessary. How it should be done?

Do I understand correctly: You have a picture with some white areas and you want to get them. Is it important that one of the objects is a circle? Or do you simply search all white areas. The later is quite trivial for a binary image, isn't it?
