Well hell . . . I'd probably use bwareaopen on your segmented (binary)
image, what about you? Median filter maybe?

@Image, any idea on how to build median filter

for n = 1+r:N-r
for m = 1+r:M-r
% Extract a window of size (2r+1)x(2r+1) around (m,n)
w = x(m+(-r:r),n+(-r:r));

% ... write the filter here ...


y(m,n) = result;
end
end

Yes, but why would I when MATLAB has the built-in medfilt2() function?
