How to show all jpg images saved in MATLAB folder?

 storedStructure = dir('*.jpg')

How should I proceed?

[Stephen23]

What do you mean "show all jpg images" ? If you have a thousand images, displaying them all at once could be a bit bewildering.

Yes, it may be. But still I want to know how can I do this?

Answer 1

This displays all of the jpg images in the current directory:

S = dir('*.jpg');
for k = 1:numel(S)
    figure();
    image(imread(S(k).name))
    axis('image');
end

Note: this code will not work with indexed image formats.

Thank you!

Perhaps one of the submissions creating thumbnails (into tables guis or the like) found on the file exchange does what you want: Thumbnaily submissions

(Almost) straight from the docs for montage:

% Create a montage from a series of JPG images in a directory
targetpath = fullfile(matlabroot,'toolbox','images','imdata','*.jpg');
imds = imageDatastore(targetpath);
montage(imds);

Alternatively, without using imageDatastore():

% Create a montage from a series of JPG images in a directory
targetpath = fullfile(matlabroot,'toolbox','images','imdata','*.jpg');
S = dir(targetpath);
allpaths = fullfile({S.folder},{S.name});
montage(allpaths);

In either case, if you want to actually save the output to a new image file, don't use montage(). Use imtile() instead and save the result using imwrite(). Most of the syntax overlaps between the two, so it should be fairly straightforward.

+1 neat idea.

ls *.jpg

if you just want to list them to the screen.

[Explorer]

No, I do not want their names. I want to show images.
