Hi, i need to divide all 5 images into 16x16 block, then perform "minus" operation (i.e 1st from 3rd image, then calculate "mean").Likewise for (3rd and 5th image) and (2nd and 4th image) using block process

See mat2cell() and cellfun()

Thanks a lot sir, i have tried code using those 2 function, please check whether it is correct.
n=16*ones(1,16)
k=[img1 img2 img3 img4 img5]
for i=1:length(k)
blockres(i)=mat2cell(i,n,n)
end
for p=1:length(blockres)-2
for q=2+p:length(blockres)
minus(p)=cellfun(@minus,p,q,'uniform',0)
end
sum(p)=cellfun(@sum,minus,'uniform',0)
end
mean(p)=cellfun(@mean,sum,'uniform',0)

Sorry sir,i noticed that from comment, but i not corrected in my code. n=16*ones(1,16) k={img1 img2 img3 img4 img5} for i=1:length(k) blockres(i)=mat2cell(k{i},n,n) end for p=1:length(blockres)-2 for q=2+p:length(blockres) minus(p)=cellfun(@minus,p{blockres},q{blockres},'uniform',0) end mean(p)=cellfun(@mean,sum,'uniform',0) end

k sir. n=16*ones(1,16) k={img1 img2 img3 img4 img5} for i=1:length(k) blockres(i)=mat2cell(k{i},n,n) end for p=1:length(blockres)-2 for q=2+p:length(blockres) res1(p)=cellfun(@minus,p{blockres},q{blockres},'uniform',0) end res2(p)=cellfun(@mean,sum,'uniform',0) end
