Hello,

Please i am trying to save multile images generated by the code.

I want the number of the image to start from 1 but its starting from 16.

Can someone out there please help.

new_I=imresize(I,[381,3041]);
    S=190;
    m=2;
    n=16;
   
    for j = 1:m
        for i = 1:n
            row1 = (j-1)*S+1 ;
            row2 = row1 + S ;
            col1 = (i-1)*S+1 ;
            col2 = col1+S;
            PR_NB = new_I (row1:row2 , col1:col2, :);
            
        base_name = sprintf('%s_%i.jpg',char(org_name(end)),n);
        full_name = fullfile (newfol, base_name);
        fprintf('Saving %s\n', char(full_name));
        imwrite( PR_NB, char(full_name)) ;
        n=(n+1)
     end
end    

Thanks

Then do not use n as counter, but another one:

iFile = 1;
...
    base_name = sprintf('%s_%i.jpg', org_name{end}, iFile);
    full_name = fullfile(newfol, base_name);
    imwrite( PR_NB, full_name) ;
    iFile = iFile + 1;
