No, I want to background of this image is only black and egg is white. how to removed interferences out of the image.

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
