how to save multiple images in different folders using a loop?

Hello everyone, I am new in image processing and I want help. I have a folder (dataset) that contains 1000 images and I want to insert noise 'salt & pepper' with different density noise (0.01,0.02 and 0.03) , I used this line to do this:

    im = imread('C:\Users\SAMSUNG\Desktop\AHTD3A0002_Para1.tif');
     J = imnoise(im,'salt & pepper',0.01);

Please help me to do this : I want to save the result in 3 folder ( data1 contains images after noise with d=0.01, data2 contains images after noise with d=0.02 and data3 contains images after noise with d=0.03).

any suggestation and thanks in advance

Try This Code:

% Creating 3 New Folders

StoreDrive = 'D:';
ImgLoadDrive = 'C:\Users\SAMSUNG\Desktop\AHTD3A';
d = [ 0.01 0.02 0.03 ];
FolderNames = {'data1','data2','data3'};

for i=1:3
    % FolderNames(i) = sprintf('data%01d',i);
    Folder = fullfile(StoreDrive,FolderNames{i});
    mkdir(Folder);
end

for i=1:1000
    %we will read image once apply salt and pepper 3 times
    %and then store images in different folder
    ImgName = sprintf('%s%04d_para1.tif',ImgLoadDrive,i);
    im = imread(ImgName);

      for k=1:3
      J = imnoise(im,'salt & pepper',d(k));
      ImgStoreName = sprintf('%s_%04d.tif',FolderNames{k},k);
      ImgStoreName = fullfile(StoreDrive,FolderNames{k},ImgStoreName);
      imwrite(J,ImgStoreName);
      end

end

Here I am creating 3 folders data1,data2 & data3 in D: drive.

Also I a assuming that your images are in this format:

AHTD3A0001_Para1.tif, AHTD3A0002_Para1.tif, AHTD3A0003_Para1.tif, AHTD3A0004_Para1.tif...

Hope this will help.
