lear all; close all;

inputfilename ='back_5.jpg';

img = imread(inputfilename);

dim = size(img);

width = dim(2);height = dim(1);

gfrgb = imfilter(img, fspecial('gaussian', 3, 3), 'symmetric', 'conv');

cform = makecform('srgb2lab', 'AdaptedWhitePoint', whitepoint('d65'));

lab = applycform(gfrgb,cform);

l = double(lab(:,:,1));

a = double(lab(:,:,2));

b = double(lab(:,:,3));

li = cumsum(cumsum(l,2));

ai = cumsum(cumsum(a,2));

bi = cumsum(cumsum(b,2));

sm = zeros(height, width);

sm2 = zeros(height, width);

for j = 1:height

yo = min(j, height-j);

y1 = max(1,j-yo); y2 = min(j+yo,height);

for k = 1:width

xo = min(k,width-k);

x1 = max(1,k-xo); x2 = min(k+xo,width);

invarea = 1.0/((y2-y1+1)*(x2-x1+1));

lm = iisum(li,x1,y1,x2,y2)*invarea;

am = iisum(ai,x1,y1,x2,y2)*invarea;

bm = iisum(bi,x1,y1,x2,y2)*invarea;

%---------------------------------------------------------

% Compute the saliency map

%---------------------------------------------------------

sm(j,k) = (l(j,k)-lm).^2 + (a(j,k)-am).^2 + (b(j,k)-bm).^2;

end

%figure()

%imshow(sm,[]);

img = (sm-min(sm(:)))/(max(sm(:))-min(sm(:)));

imwrite(img,'back_msss.jpg')

now i have six faces like top, front ,bottom, back,left, and right

i need to save images in different folders with image names as top.png, right,png

As far as I understand, the posted code has no relation to the actual problem.

What is the problem with saving the images to different folders?

imwrite(img, 'D:\Your\Folder\top.jpg')

You can do this, as Jan hinted at, something like this:

faces = 1:6
face_names = {'top','bottom','front','back','left','right'}; % your image-names
folders2savein = {'run-01','run-02'}
for iRuns = 1:2 % or however many sets you might need
    for iFaces = 1:numel(faces)
        % Here's where you plug in your processing, for each face and whatever you need
        img_type = 'msss'; % In case you have multiple result-files to save
        savename = fullfile(folders2savein{iRuns},...
                            sprintf('%s_%s.jpg',face_names{iFaces},img_type));
        imwrite(img,savename)
    end
end

By using fullfile your code will become robust enough to run in different operating systems, and that's one worry less, by generating the file-name this way where you put toghether different parts of the name you're preparing to use this for cases where you save a number of different outputs from the same run and face. Doing it this way will make batch-processing much cleaner.
