Hi everyone,

I have 3 different folders, each folder includes 100 images (image-1 to image-100).

I want read image-1 (from folder 1), image-1 (from folder 2) and image-1 (from folder 3).

Finally, I want to display 3 images together in figure 1? (image-1 show together image-1, image-2 show together image-2...)

Thank you for your help.

How are your images stored? Are the Matlab Figure files or are the something else (like png, jpg, etc.)?

all is .bmp.

Folder1: image-1.bmp, image-2.bmp...

Folder2: image-1.bmp, image-2.bmp...

Folder3: image-1.bmp, image-2.bmp...

Now, i want to read and show in one figure. (3 images image-1.bmp together, 3 images image-2.bmp together...)

在 MATLAB Online 中打开

selpath = uigetdir; % or selpath = '<your directory full path>';
n_images = 100;   % number of images 
for ii = 1:n_images
    figure(ii), 
    file = strcat('image-', num2str(ii), '.bmp');
    img1 = imread(fullfile(selpath, 'Folder1',  file));
    img2 = imread(fullfile(selpath, 'Folder2', file));
    img3 = imread(fullfile(selpath, 'Folder3', file));
    subplot(311), imshow(img1), title(strcat('from folder 1 ', file));
    subplot(312), imshow(img2), title(strcat('from folder 2 ', file));
    subplot(313), imshow(img3), title(strcat('from folder 3 ', file));
end

What if you have too many files to hard code each one?
