image iteration

Hi there, I have this set of images as shown, I found the centroid of each by using the code below, now I stored the new images in Im01,Im02,Im03, and they are all N by N matrix images.

Im1 = imread('image1.png');

[x,y] = ait_centroid(Im1);

Im01=circshift(Im1, [-1 -5]);

[x,y] = ait_centroid(Im01);

Im01=uint16(Im01);

Im2 = imread('image2.png');

[x,y] = ait_centroid(Im2);

Im02=circshift(Im2, [-2 -4]); [x,y] = ait_centroid(Im02);

Im02=uint16(Im02);

Im3 = imread('image3.png'); [x,y] = ait_centroid(Im3); Im03=circshift(Im3, [-3 -5]); [x,y] = ait_centroid(Im03); Im03=uint16(Im03);

 my challenge is how to add this images using iteration cos i hav a large set of images(not jst the 3 images) im working on.I was able to add them manually n show the mean by doin this

G=imadd(Im01,Im02,'uint16'); G=imadd(G,Im03,'uint16'); imshow(uint8(G/3),[]);

and it worked.But when I tried iterating by doin this

G=imadd(Im01,Im02,'uint16'); for i=1:1:3 G=imadd(G,Im(i),'uint16'); end

I get error, I also tired to define the images as a matrix of a matrix by

H = [ [Im01] [Im02] [Im03] ] G=imadd(Im01,Im02,'uint16'); for i=1:1:3 G=imadd(G,H(i),'uint16'); end image error indicates in H(i)..Please I need help, thanks.

Thanks for the links,have seen before,I do understand some of the explanations but I haven't been able to achieve my aim because I cant interpret some of the codes, Im still learning matlab.

Where you have Im01 change it to Im{1} . Where you have Im02, change it to Im{2}. Where you have Im(i) change it to Im{i}

Thanks a bunch.It worked!
