How to saveas multiple figure in folder using matlab ?

I want to save the figure in .jpeg format in a new folder. i get an error in this code. please help me to solve this problem. I would be very grateful.

image_folder ='E:\Resize 200' 
filenames = dir (fullfile(image_folder,'*.jpeg'))
total_images = numel(filenames);

for n= 1:total_images;
   f= fullfile(image_folder, filenames(n).name);
   
ambang = 40; % ambang mulai dianggap bagian badan 
citra = imread(f);
[tinggi, lebar] = size(citra); % ukuran citra

%figure; imshow(citra);

baris_tengah = citra(floor(tinggi / 2), :); % baris tengah citra
kiri = 1; % nilai awal batas kiri
kanan = lebar; % nilai awal batas kanan

for i = 25:lebar % cari dari kiri
  if baris_tengah(i) > ambang % kalau sudah tercapai,
    kiri = i; % simpan letaknya
    break; % berhenti cari
  end;
end;

for i = (lebar - 25):-1:1 % cari dari kanan
  if baris_tengah(i) > ambang % ,
    kanan = i; % 
    break; % 
  end;
end;

%figure; hold on;
%plot(baris_tengah);
%plot([kiri kiri], [0 255], 'r'); % batas kiri
%plot([kanan kanan], [0 255], 'r'); % batas kanan
%hold off;

%hasil pangkas
pangkas = imcrop(citra, [kiri 0 (kanan - kiri) tinggi]);
figure; 
imshow(pangkas);


saveas (figure, 'baru',f(i));
end

Hello,

Witouth the figures or the error message it's not really clear which error you obtain. But at first glance the saveas command doesn't seem correct. The variable f holds the full filename of the original picture, and you ask the i'th element from that.

Can you try to change the command into something like:

    currFig = figure;
    imshow(pangkas);
    saveas(currFig, fullfile(image_folder, ['baru ' filenames(n).name]));

By doing so you basically append the original filename with "baru". Note that this will save it in the orginal folder, but with a different name.
