How can I fill the gaps in a binary image?

I want to fill the gaps in this image and make the edges smooth. With no black islands in the while region or white islands in the black region.
I tried "bwconvhull", but it didn't conserve the shape of the image, it converted the image to a white rectangle-like shape.

An imclose with a fairly large structuring element might be what you're after, something like:
imclose(yourbinaryimage, strel('disk', 10))
You might want an imopen with a smaller structuring element beforehand to remove the small white isolated islands.
