Hi sir i have this program to normalized the databese of images but when i run this program i have the error in :S(:,i)=(temp-m)*std/st+m; if you help me sir and thank you a lot ????
temp=reshape(img',irow*icol,1);
%S will eventually be a (N1*N2) x M matrix.
S=[S temp];
%Normalize.%Normalize.
for i=1:size(S,2)
temp=double(S(:,i));
m=mean(temp);
st=std(temp);
S(:,i)=(temp-m)*ust/st+um;
end

Well, yes, given the code you provided they are undefined. The error message tells you precisely what the problem is!
