  • the egg is clear so its pixels should be equal to 255. so you hould to put other pixels to 0 (which is black).
input=imread(image) if input(i,j)~=255 then input(i,j)=0 i think this should work

threshold=25;
for f=1:frames
I=read(obj,f);
figure(1);imshow(I);title('Input Video Sequence');
if f==1
Background=I;
Fg=abs(I-Background);
else
Fg=abs(I-Background);
end
Fg(Fg>threshold) = 255;
Fg(Fg<=threshold) = 0;
figure(2);imshow(Fg);
drawnow;
pause(0.2)
end

See my attached demo to extract the biggest blob in the image. That will pull out just the egg and not all the other clutter.
