How to sort images from a folder in subfolders using the data from a excel/ .mat file?

Hello, I have a dataset with flowers (8000 pictures) and i need to sort them in subfolders (rose, tulip, etc) and i have the imagelabel.mat witch is a double value (1x8000) where i can see how many examples are for each class. How can i sort them without having to create folders and copy-paste the images in folders? A code example would help a lot. Thanks

You need to iterate through your dataset and ensure the necessary subfolder exist, then move the file

% concat sub folder path
subfolderPath = [parentDirPath '\' flowerName];

% check if subfolder exists
if ~exist(subfolderPath, 'dir')
  % create subfolder
  mkdir(subfolderPath);
end

% move file from original path to subfolder
[status, msg] = movefile([parentDirPath '\' fileName], [subfolderPath '\' fileName]);

% check if file moved successfully
if ~status
   % log error
end

That's the general idea

There are no subfolders, I have to generate them from script, but how does the script access the data from imagelabel.mat to know where to move the images?

I edited the code to make it clearer.

To read data from .mat file use the load function

ok, but do i need to use

    [status, msg] = movefile([parentDirPath '\' fileName], [subfolderPath '\' fileName]);

for each image? they are named image_0001 and so on. I was hoping that the script will sort them automatically by using the data i provided in .mat file

You will have to loop through your data and do that for each file

for i = 1:length(yourData)
  % use above code
end

I don't know the names of your variables or how your data is saved or anything else about it.

That's the general idea
