Group files with same names
显示 更早的评论
I have a folder with images of different models of cars(20 to be specific). For each car model I have 100 sample images. They are all in a single folder and named:
Audi_01, Audi_02, ...... , Audi_100
Lexus_01, Lexus_02 ...., Lexus_100
...
How can I group same model cars and put them in a new folder.
I tried : copyfile Audi*.jpg Audi
But, for that I have to type and run the command for 20times.
Is there any alternative way or command in matlab?

Folder = 'D:\Your\Data\Folder';
FileList = dir(fullfile(Folder, '*.jpg'));
FileName = {FileList.name};
Name = unqiue(strtok(FileName, '_'));
for iName = 1:numel(Name)
mkdir(fullfile(Folder, Name{iName}));
match = startsWith(FileName, [Name{iName}, '_']);
Group = FileName(match);
for iGroup = 1:numel(Group)
copyfile(fullfile(Folder, Gorup{iGroup}), fullfile(Folder, Name{iName}));
end
end
