A graphics that shows what you want to do would be helpful.

The image you included has content that I cannot relate with your question.

I don't even know what "fill with a different diameter" means, but you might try imfill

mask = imfill(mask, 'holes');

Why do you wan tto do this? And your image is of such low resolution it's hard to see what's going on but somehow I guess you've drawn circles inside the white outline, right? Can you attach higher resolution images, both with and without the red circles?

Have you tried viscircles?

If you want to know the largest circle that can fit at any point in the image you can use bwdist which tells you the distance in pixels from every point in the shape (you need to fill it first with imfill) to the nearest edge/border pixel.
