Details:

I have installed image toolbox 1.0.10, and found that bwfill is not working
for filling holes. Here is a quick test

dat=zeros(60);
theta=0:pi/360:2*pi;
ix=20*sin(theta)+30;
iy=20*cos(theta)+30;
dat(sub2ind(size(dat),floor(ix),floor(iy)))=1;

figure
imagesc(dat)
dat2=bwfill(dat,'holes');
figure
imagesc(dat2)

the same script works perfectly in matlab.
