Putting cropped images in seperate folder

Hi,

I cropped images with size 200 x 200 into 4 tiles with 50 x 50 for each tile and i want to make these generated tiles into seperated folder

Herein the code

close all;
clc; 
 %%  Initalize the data 
 dataDir= fullfile('Data/');
exts = {'.jpg','.png','.tif','BMP'};
 imds = imageDatastore(fullfile(dataDir),...
'IncludeSubfolders',true,'FileExtensions','.jpg','LabelSource','foldernames');
countEachLabel(imds);
 [TrainData, TestData] = splitEachLabel(imds,0.5);
size(TrainData);
countEachLabel(TrainData);
numImages = numel(TrainData.Files); 
dx = 50;
dy = 50;
w = dx - 1;
h = dy - 1;
for i = 1:numImages
    img = readimage(TrainData, i);
    img=rgb2gray(img);
    img3= im2double(img); 
    scale = 0.5;
    img8 = imresize(img3,scale);
    for x = 0:2
        for y = 0:2
            ofs_x = 1 + x * dx;
            ofs_y = 1 + y * dy;
            img_crop = imcrop(img8,[ofs_x ofs_y w h]);
            %img4 = imshow(img_crop, 'InitialMagnification',800);
            %drawnow;
            idx = (i-1)*4 + y*2 + x + 1;
            % 1  2  4  5
            % 6  7  8  9 
            % 10 11 12 13
            % 14 15 16 17            
            Train{idx} = (img_crop);         %#ok<SAGROW>
        end
    end 
end

The code Train{idx} is the for generated tiles 50 x 50

Hi Abdussalam,

As per my understanding you need to put the cropped tiles in Train variable into another folder. I am assuming that you are trying to do that as an .jpg file. The below code would help you to the same.

mkdir croppedImages
for i = [1:size(Train,2)]
    K = mat2gray(Train{i});
    imwrite(K,"croppedImages/"+string(i)+".jpg",'jpg');
end
