- Get a directory listing of all the files in your source folder.
- Read the workbook and get the class label from the appropriate column - the CSR column.
- Build a new destination filename using the class label as a folder.
- Use a for loop and copyfile to copy the files.
Something like (untested)
filePattern = fullfile(inputFolder, '*.png');
imds = imageDatastore(filePattern);
t = readtable(workbookName);
classFolderNames = t.CSR;
allFileNames = imds.Files;
for k = 1 : numel(allFileNames)
% Get input file name from datastore.
sourceFileName = allFileNames{k}
[folder, baseFileNameNoExt, ext] = fileparts(sourceFileName);
% Get class name from workbook.
% Assuming the order of class assignments matches up with that in the
% datastore (NOT a good assumption though), you can do this
subFolderName = classFolderNames{k};
destinationFolder = fullfile(folder, subFolderName);
if ~isfolder(destinationFolder)
% Create subfolder if it does not exist.
mkdir(destinationFolder);
end
% Build destination file name
destinationBaseFileName = [baseFileNameNoExt, ext]; % Same name as input
destinationFullFileName = fullfile(destinationFolder, destinationBaseFileName);
% Copy file into output folder.
copyfile(sourceFileName, destinationFullFileName);
fprintf('Copied "%s" to \n "%s".\n', sourceFileName, destinationFullFileName)
end
