Do you want to find the shape of the egg? Do you have the image processing toolbox?

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

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.
