I have a structure like above image.
the structure is that load all jpg files in folder.
(so many files i have, so i want to read automatically.)
but, I can't use structure.
I want to variables.
I try this.
a = dir('C:~~~~~\*.jpg');
for i = 1 : length(a)
filename = strcat('C:~~~~\',a(i).name);
I = imread(filename);
end
finally, what I want is same result of imread.
image(i) = ~~~~ % = imread('~~~.jpg'
image(2) = ~~~~
...
image(n) = ~~~~

Heo - try the following. Create a cell array outside of your loop to store the data that you read on each iteration of the loop. Something like
myFolder = pwd;
myFiles = dir([myFolder '/*.jpg']);
myImages = cell(length(myFiles),1);
for k=1:length(myFiles)
filename = fullfile(myFolder,myFiles(k).name);
myImages{k} = imread(filename);
end
The above uses pwd to get the current directory and looks for all jpg files within it. We then pre-size the myImages cell array to populate with each read image. fullfile is used to correctly build the path to the file of interest. Try the above and see what happens!
