MORPH_CLOSE did not work for this? Out of curiosity, did you apply it to
your original image or to the bi-level region mask?

You might try to SMOOTH the image, or you can reduce the colors in it. You
mentioned this is an unsigned integer image; that's a lot of gray levels, do
you need them all? If the regions are truly almost uniform in gray level,
reducing the number of grays might get rid of the noise.
